When Malia Baker moves in with her mom's new fiancé, the last thing she expects is Kylie Cantrall-her gorgeous, maddening, soon-to-be stepsister. Kylie is everything Malia can't stand: arrogant, untouchable, and perfectly content to make Malia's life as difficult as possible. But beneath the biting remarks and stolen glances, there's something electric neither of them can deny. Kylie has spent her life hiding behind a polished facade, keeping the world-and her emotions-at arm's length. But Malia's sharp wit and quiet strength unravel her defenses, one infuriating encounter at a time. Forced to share a home, they're drawn together by secrets they're afraid to share and a tension they can't escape. In a house full of boundaries, will they break the rules-or each other?
