romance books with toxic but addictive relationships
May 19, 2026toxic romance is one of the most searched dark romance categories right now — and the books that do it well are the ones that make you question why you can’t stop reading.
if you’re looking for a healthy relationship, you’re in the wrong place.
these are the ones where love crosses lines, where obsession takes over, and where he or she would burn the world down without a second thought.
what you’ll find in this list
these aren’t the kind of books that comfort you. they pull you in, keep you on edge, and make it impossible to look away.
my take
if i’m not at least slightly concerned for everyone involved… it’s not toxic enough.
the books
born darkly is obsessive, concerning, and addictive in ways it probably shouldn’t be.
Born, Darkly
a criminal psychologist and a convicted serial killer form a twisted connection built on intellect, control, and mutual fascination.
souls in ruin will have you questioning why you relate so much to the fmc who can’t choose between her tormentor and the man behind the wall.
Souls in Ruin
married off to a cold king and trapped in her own kingdom, she’s forced to survive two dangerous men… and prove she was never meant to break.
the annihilator is book five in the series, and i highly recommend starting from the beginning. but once you get here, it’s worth it.
start with book one of the dark verse
The Annihilator
a ruthless man who rules the shadows becomes obsessed with the one girl who lives in them… and decides she’s his.
lawless god feels like the definition of stockholm syndrome in its most addictive form.
Lawless God
she’s the reason he went to prison, and when he finally gets out, the first thing he does is come back for her.
the words is the least dark on this list, but not the least toxic. broken people trying to piece themselves back together.
The Words
years after he made her feel seen and then shattered her, a former outcast is forced back on tour with the man who ruined her.
insatiable if you haven’t read this yet and want something truly toxic but addictive, start here.
