Enter Elias Vance: her best friend's older brother, a billionaire architect, and the most emotionally repressed man in Boston. Elias offers her his spare room, but it comes with a catch—a literal leather-bound Rulebook designed to maintain his pristine, silent, and perfectly controlled penthouse. Hazel is messy, chaotic, and everything Elias avoids. But as rules are broken and their forced proximity sparks an undeniable, burning tension, Elias realizes the one variable he can't control is his heart. Can the Ice King survive the chaos of falling in love?"
