What about non-fiction that reads like a psychological thriller? 'The Stranger Beside Me' by Ann Rule. The toxic relationship here is between Rule herself and Ted Bundy, whom she knew personally before his crimes were revealed. The book details her dawning, horrific realization that the charming, helpful man she considered a friend was a monster.
The psychological detail is in her own process of cognitive dissonance. How do you reconcile two utterly irreconcilable truths about someone? It's a masterwork of true crime because the thriller element is real, and the toxic dynamic is one of deception on a monumental scale. It's the ultimate betrayal of trust, documented by someone who lived it.

Hmm. Not sure I have a full list handy, but I'm definitely following this thread. Saw the notification and had to click because I've been meaning to dig into this exact category. Hope some folks drop titles with those unsettling, quiet-burn vibes rather than just the shock-value stuff.

Tana French's 'The Likeness' offers a weirdly compelling toxic bond within a group of friends. The relationship between the four main characters and the victim, Lexie, is claustrophobic and codependent. Detective Cassie Maddox's infiltration into this group shows how identity can be eroded by the desire to belong.
The toxicity is in the shared fantasy, the unspoken rules, and the way the group consumes individuals. It's a slow-burn psychological thriller where the danger is emotional assimilation.

Finally, 'The Night She Disappeared' by Lisa Jewell. While it's a missing-person mystery, the toxic relationship between the young couple who vanishes is a central puzzle. The story alternates between the search and the events leading up to their disappearance, revealing a relationship strained by ambition, jealousy, and outside pressures.
The toxicity isn't overtly abusive but a slow erosion of trust and happiness. The book also explores the toxic dynamics within the affluent community where it happens. Jewell is a master at creating ordinary characters caught in extraordinarily sinister situations.

For a pure, adrenaline-fueled chase, 'No Exit' by Taylor Adams. College student Darby is stranded at a rest stop during a blizzard and discovers a child locked in a van. The toxic relationships are between the strangers trapped with her—one of whom is a kidnapper. The 'romance' is nonexistent; it's all about survival and unlikely alliances. The danger is immediate, claustrophobic, and brutally physical. It's a single-setting thriller that doesn't let you breathe.
You'll read it in one tense sitting.

The audiobook narrator for 'The Whispers' used this barely-there vocal fry for the male character's 'caring' lines that made my skin crawl. It was pure genius. You could hear the condescension.

Dorothy Koomson’s ‘The Ice Cream Girls’ and ‘My Best Friend’s Girl’ are standalones, but they delve into incredibly complex female relationships that feel sisterly or maternal, and how those bonds can become prisons. The toxicity is often wrapped up in shared guilt, protectiveness that turns possessive, or societal pressures.
They’re more psychological dramas with thriller elements, but the suspense comes from the emotional time bombs waiting to go off between characters who know each other’s deepest shames. It’s a quieter, more heartbreaking kind of thrill, where the biggest betrayal isn’t always a murder—it’s a secret kept or a truth withheld.

You might like 'Bunny' by Mona Awad. It's a dark academia satire with horror elements. The relationships within the 'Bunny' clique are intensely toxic, built on collective delusion, manipulation, and a horrific form of creative collaboration. The power is in the groupthink, the social exclusion, and the surreal demands of belonging. The 'love' between the girls is obsessive, consuming, and literally transformative in a body-horror way. It's a wild, unnerving ride about the horrors of fitting in.

A lot of recommendations focus on the woman-as-victim or the femme fatale trope. For a change, try 'The Kind Worth Killing' by Peter Swanson. Two strangers on a plane jokingly plot a murder, and the psychological game that unfolds is ruthless, twisty, and involves multiple perspectives, including a fantastically amoral female character. The romantic entanglements are purely strategic, weapons in a game of survival and revenge. It's a cold, calculated, and brilliantly plotted book where every relationship is a move on a chessboard. You'll constantly be guessing who is playing whom.
