Stupid sister, ILY

Have you ever been trapped by a promise you never agreed to-one made for you by someone who's already gone?
When Harper's father dies, his will drags her back into the last place she wants to be: the family estate she must share with her stepbrother. Jaxson is the boy she never allowed herself to love, the mistake she buried deep, the memory that still burns. Bound by their father's final demand, they're trapped under the same roof, surrounded by resentment and a desire that was wrong then-and even more dangerous now.
Harper tells herself she's moved on. She has a boyfriend who fits perfectly into her life on paper, a man who looks right beside her and feels wrong behind closed doors. While she lies awake, unsatisfied and restless, Jaxson is just down the hall-dark, reckless, and painfully aware of everything she's denying. Every argument crackles with tension. Every shared space becomes a test of control. Hate slowly mutates into obsession, and proximity becomes impossible to survive untouched.
This is a dark, forbidden romance where stepsiblings collide, enemies burn into lovers, and obsession thrives behind closed doors. Featuring forced cohabitation, a love triangle, sexual frustration, a dangerous bad boy, and a pull that defies morality, this story is for readers who crave tension, taboo, and the kind of love that feels like a mistake you'd make again anyway.
