Rating: ⭐⭐⭐⭐½ (4.5/5 Stars - The "I Need Therapy But Also Book 2" Award) Spice Rating: 🌶️🌶️🌶️🌶️🌶️ (5/5 - Bring Holy Water and a Fire Extinguisher) Plot Rating: 📖📖📖📖 (4/5 - Compelling But Could Use More Development)
Let me start by saying this: if you pick up "Across State Lines" by Lauren Biel expecting a cute road trip romance, you're in for the shock of your life. This is not that book. This is the book that makes you question your moral compass, your taste in literature, and possibly your sanity. This is the book that has you Googling "is it normal to root for a serial killer?" at 2 AM while simultaneously texting your book club, "GUYS, I NEED TO TALK ABOUT THIS RIGHT NOW."
Welcome to the wild, morally bankrupt, psychologically fascinating world of Kane (and Jax, and Tobin), a long-haul trucker with Dissociative Identity Disorder who's left a trail of bodies along Interstate 90, and Aurora, a college dropout turned sex worker who's about to become either his next victim or his salvation. Spoiler alert: It's complicated. Very, very complicated.
What Fresh Hell (Literally) Is This About?
Picture this: You're Aurora, a young woman who dropped out of college after a traumatic assault, and you're trying to make your way across the country back home to New York. You're broke, you're desperate, and you've been surviving by selling your body at truck stops. It's not glamorous, it's not safe, but it's keeping you alive. Then you meet a sweet, gentle man named Jax at a diner who seems genuinely kind. Later, you encounter a gruff, intimidating trucker named Kane who offers you a ride.
Here's the twist: They're the same person. Well, sort of. Kane has Dissociative Identity Disorder (DID), and his mind has fractured into multiple distinct personalities to protect him from childhood trauma so horrific that his psyche literally couldn't handle it. There's Kane—the cold, calculating serial killer who's murdered hundreds of sex workers along the interstate. There's Jax—the sweet, caring personality who wants to protect and nurture. And there's Tobin—the hypersexualized alter who's equal parts sadist and protector, born from sexual trauma and existing to handle what Kane cannot.
When Aurora gets into Kane's truck, she unwittingly becomes his next intended victim. But something's different this time. Tobin wants to keep her. Jax is falling for her. And Kane? Kane is struggling to maintain control as his carefully constructed equilibrium crumbles around him.
What follows is a psychological thriller wrapped in a dark romance, exploring trauma, survival, the fragility of the human mind, and whether love can exist in the darkest corners of human experience. It's "Criminal Minds" meets "Fifty Shades" meets a psychology textbook, and somehow it works.
The Characters: A Study in Fractured Humanity
Kane: The primary personality and the one in control most of the time. Kane is a long-haul trucker who's built a life for himself despite (or because of) his fractured psyche. He's methodical, cold, and has killed hundreds of women—specifically sex workers who "no one will miss." As he chillingly notes: "And like I said, no one ever misses them. They don't have anyone."
Kane doesn't like to be touched. He can't handle intimacy. The only time he touches women is when he's strangling them. He's the darkness, the killer, the part of the psyche that's given up on humanity. But as the story progresses, we see glimpses of something more—a man who's terrified of feeling, of connecting, of being vulnerable.
Jax: The light in the darkness. Jax is described as "the light I could never shine on this world." He's gentle, caring, and handles social situations that Kane can't manage. He's the one who can show compassion, who can love without fear. When Aurora meets Jax first, she's drawn to his kindness, his genuine concern. Jax is the personality that makes you believe redemption is possible.
Tobin: Oh, Tobin. This is where things get WILD. Tobin is the hypersexualized alter, born from sexual trauma, and he's absolutely unhinged in the best and worst ways. He's a sadist who finds pleasure in pain, both giving and receiving. He's filthy, depraved, and completely unapologetic about it. As one quote captures: "Eating pussy is a Jax move, but I'll eat her come-filled asshole all day." (Yes, that's an actual quote. Yes, you read that correctly. No, I'm not sorry for sharing it.)
But here's the thing about Tobin—he's also a protector. He sees himself as the one who keeps the others safe, who can handle the sexual aspects of life that Kane can't touch. He's complex, fascinating, and will either be your favorite or the reason you DNF this book.
Aurora: Our heroine is a survivor in every sense of the word. She's been through hell—gang-raped in college, dropped out, estranged from her family, and now selling her body to survive. But Aurora isn't broken. She's fierce, snarky, and refuses to be a victim even when she's literally in the truck with a serial killer.
What makes Aurora compelling is her strength. She doesn't just survive Kane's attempts to break her—she pushes back. She's smart enough to navigate the dangerous waters of three distinct personalities, brave enough to stand her ground, and damaged enough to understand their darkness. As one reviewer perfectly stated: "Trauma recognizes trauma. You aren't fragmented the same way we are, but you're just as broken."
Pup: The three-legged dog who belongs to Kane and becomes the unexpected catalyst for connection. Pup is the softest thing in this dark story, and his presence humanizes Kane in ways nothing else can.
The Plot: A Road Trip Through Hell (With Orgasms)
The plot is deceptively simple: Aurora gets in Kane's truck, and over the course of their journey across state lines, a twisted relationship develops. But the execution is anything but simple. Lauren Biel has crafted a psychological thriller that explores the nature of identity, trauma, and whether love can exist between people who are fundamentally broken.
The story unfolds through dual POV, giving us insight into both Aurora's survival instincts and the internal battle between Kane's personalities. We see Tobin leave notes for Kane. We watch Jax try to protect Aurora from Kane's murderous impulses. We experience Aurora slowly realizing that she's not dealing with one man, but three distinct individuals sharing the same body.
The tension is constant. Will Kane kill Aurora? Can she escape? Should she even want to? As the personalities vie for control and Aurora navigates this psychological minefield, the story becomes less about physical survival and more about emotional connection in the most unlikely circumstances.
There's also a subplot involving "the nameless"—a group of brothers Kane owes money to, whom he pays off by selling them women. This adds another layer of danger and raises the stakes considerably. Kane initially plans to sell Aurora to them, but as his alters develop feelings for her, that plan becomes increasingly complicated.
Quotes That Will Haunt You (In Multiple Ways)
Lauren Biel has a gift for writing lines that are simultaneously disturbing and oddly poetic. Here are some actual quotes from the book:
"Trauma recognizes trauma. You aren't fragmented the same way we are, but you're just as broken."
"If I'm doomed to die at his hands, I might as well enjoy a few orgasms from those same hands as well." (Aurora's survival philosophy in a nutshell)
"Just let me go. I won't tell anyone. I swear."
"It's a bit late for that. I can't let you go now that I've seen how terrified you are. I drink up fear like it's liquor. Right now, you're a bottle of Everclear. And I'm a fucking alcoholic tonight."
"There isn't enough time to tell her all the ways I love her, so I'll just have to show her."
"Home is here in this truck. Home is Kane, Tobin, and Jax. Home is a little dog who ran away and brought four people together."
"I may be the prey who wormed her way into his blackened heart, but he's still a predator."
"Breaking her became a challenge for me, but she never stopped being a snarky bitch, even in the face of death."
"You broke through to the big, bad serial killer. Can we let it go now? I think I'm all talked out."
And my personal favorite for its sheer absurdity: "Besides, with the way Kane kills, the least of our problems is some come-laced ice cubes in the freezer." (Context: You don't want to know. Actually, you probably do, but I'm not telling.)
Trigger Warnings: The VERY Necessary Conversation
Before we go ANY further, we need to have a serious talk about content warnings because this book is DARK. Like, "maybe don't read this if you're in a fragile mental state" dark. Here's what you're signing up for:
⚠️ Serial killer MMC (he's murdered hundreds of women) ⚠️ Dissociative Identity Disorder representation (multiple personalities) ⚠️ Sex work (FMC is a prostitute) ⚠️ Sexual assault (off-page, in FMC's past) ⚠️ Gang rape (off-page, referenced) ⚠️ Child sexual abuse (off-page, in MMC's past) ⚠️ Extreme sexual content (degradation, humiliation, pain play) ⚠️ Dubious consent (power dynamics are EXTREME) ⚠️ Violence and murder (on-page) ⚠️ Human trafficking (mentioned) ⚠️ Psychological manipulation ⚠️ Degradation and humiliation (not always in a sexy way) ⚠️ Knife play, blood play, breath play ⚠️ Fisting, anal play, temperature play ⚠️ Bodily fluids in creative ways (I'm being vague on purpose) ⚠️ Shock collar use ⚠️ Grave play (yes, you read that right) ⚠️ Extreme kinks (the list is EXTENSIVE)
Lauren Biel provides a full list of trigger warnings on her website, and I STRONGLY recommend checking them before reading. This is not a book for everyone, and that's okay.

Why This Gets 4.5 Stars Instead of 5
Let me be clear: I loved this book. LOVED it. But I'm giving it 4.5 stars instead of 5 for some specific reasons:
What Works Brilliantly:
- DID Representation: Lauren Biel clearly did her research. Each personality is distinct, believable, and serves a purpose. The way they communicate through notes, the memory gaps, the switching—it all feels authentic.
- Psychological Depth: This isn't just a dark romance with shock value. It's a genuine exploration of trauma, survival, and the human mind's capacity to protect itself.
- Character Complexity: Both Aurora and Kane (and his alters) are fully realized characters with depth, motivation, and realistic responses to their circumstances.
- The Writing: Biel's prose is sharp, engaging, and unapologetically dark. She doesn't shy away from the uncomfortable, and she writes it with skill.
- Emotional Payoff: Despite the darkness, the ending feels earned and satisfying.
- Narration: Teddy Hamilton's performance is PHENOMENAL. The way he voices three distinct personalities is masterful.
What Holds It Back:
- Pacing: The ending feels slightly rushed. After such a detailed journey, the resolution comes quickly.
- Character Development: While the DID is well-represented, I wanted more time inside Kane's head, more exploration of his internal struggle.
- The Degradation: Some of the humiliation Aurora endures (particularly early on) crosses from dark romance into genuinely uncomfortable territory. It's not sexy degradation—it's just cruel.
- Length: At 237 pages, the book feels too short for the complexity of the story. This needed another 100 pages to fully develop the relationships and give us more of the psychological journey.
- The Romance: The shift from "I'm going to kill you" to "I love you" happens quickly. While trauma bonding is real, the emotional progression needed more time to feel fully earned.
The Spice: Extreme, Creative, and Not For Everyone
Let's talk about the heat level because it's IMPORTANT. This book is a 5/5 on the spice scale, but it's not your typical romance spice. This is extreme, kinky, often degrading, and ventures into territory that many readers will find uncomfortable or triggering.
The sexual content includes: fisting, anal play, knife play, blood play, temperature play, degradation, praise, pain play, and things involving bodily fluids that I'm not going to detail here. Tobin's scenes in particular are FILTHY and unapologetically depraved.
But here's the thing: the spice serves a purpose. It's not gratuitous (well, mostly). It shows the different ways each personality relates to Aurora, explores power dynamics, and demonstrates how trauma manifests in sexual behavior.
If you need your spice to be romantic and tender, this is NOT your book. If you're open to exploring the darker, more primal side of sexuality in a fictional context, this might work for you.
The DID Representation: Surprisingly Thoughtful
One of the strongest aspects of "Across State Lines" is how Lauren Biel handles Kane's Dissociative Identity Disorder. She clearly researched the condition and presents it with respect and accuracy. Each alter has their own distinct personality, memories, and way of relating to the world:
- Kane holds the trauma of being a killer and the need for control
- Jax holds the capacity for gentleness and emotional connection
- Tobin holds the sexual trauma and the ability to experience physical intimacy
The way they communicate through notes, the memory gaps between switches, the distinct speech patterns and behaviors—it all feels authentic. As one reviewer noted: "Lauren has written a devastatingly painful yet beautiful story that accurately portrays DID and additional traumas a person has to learn to live with and process."
The book doesn't romanticize the disorder or present it as "quirky." It shows the genuine struggle, the confusion, the pain of living with a fractured mind. It's one of the most thoughtful representations of DID I've seen in romance fiction.
The Elephant in the Room: Is This Romance or Horror?
Here's where we need to have an honest conversation: Kane is a serial killer. He's murdered hundreds of women. He picks up Aurora with the intention of either killing her or selling her to human traffickers. The power dynamic is not just unbalanced—it's a canyon.
So how does this work as a romance? The answer is: it barely does, and that's kind of the point. This isn't a traditional romance where the hero is secretly good underneath. Kane is genuinely dangerous. The book doesn't try to excuse or justify his actions. Instead, it explores whether someone this broken can be reached, whether love can exist in the darkest places, and whether redemption is possible for the irredeemable.
Aurora's acceptance of Kane and his alters isn't Stockholm Syndrome (though it flirts with that line)—it's a conscious choice made by someone who's equally damaged. She sees in them a reflection of her own brokenness, and she chooses to stay not because she's been manipulated, but because she understands them in a way no one else can.
It's uncomfortable. It's morally ambiguous. And it's absolutely fascinating.
The Verdict: A Flawed Masterpiece of Dark Romance
"Across State Lines" is not for everyone, and it shouldn't be. This is a book that pushes boundaries, challenges readers, and ventures into territory that many will find too dark, too extreme, too uncomfortable. And that's okay.
But for readers who are open to exploring the darkest corners of romance fiction, who can separate fantasy from reality, and who appreciate psychological complexity in their characters, this book is exceptional. Lauren Biel has created something unique—a romance that's also a psychological thriller, a love story that's also a horror story, a tale of redemption that doesn't shy away from the irredeemable.
The 4.5-star rating reflects a book that's nearly perfect within its niche but held back by pacing issues and a slightly rushed ending. The DID representation is excellent, the psychological depth is impressive, and the emotional payoff is satisfying. But it needed more time, more pages, more development to fully realize its potential.
Read this if you:
- Love dark romance and aren't easily triggered
- Are fascinated by psychology and mental health representation
- Can handle extreme sexual content and violence
- Appreciate morally black characters
- Want something that will challenge and disturb you
- Can separate fiction from reality
- Are looking for something genuinely unique in the genre
Skip this if you:
- Need your heroes to be redeemable or morally gray
- Are triggered by violence, sexual content, or discussions of trauma
- Prefer traditional romance dynamics
- Can't handle extreme kinks or degradation
- Need your romance to be romantic
- Want a longer, more developed story
- Prefer books that don't venture into horror territory
Final Thoughts: "Across State Lines" is Lauren Biel at her most daring. It's a book that will make you uncomfortable, make you think, and possibly make you question your own boundaries. It's not perfect—the pacing could be better, the ending could be more developed, and some scenes cross lines that even dark romance readers might find too extreme.
But it's also brilliant, brave, and genuinely unique. The DID representation is thoughtful and accurate. The psychological exploration is fascinating. And the romance, twisted as it is, feels authentic to these characters.
Four and a half stars. A near-masterpiece of extreme dark romance. Read at your own risk, check those trigger warnings, and prepare to have your brain thoroughly scrambled.
And maybe don't eat while reading this one. Trust me on that.
P.S. - Lauren Biel will ruin ice cubes for you. You've been warned.
