At her eighteenth birthday party, Sophie uses a blackout and a dare to steal a forbidden kiss from Adrian—her dangerously powerful guardian—then blames it on “night blindness.” But Adrian refuses to let her run, especially when she claims she meant to kiss her childhood friend Ryan. Their secret desire ignites through jealous games and hidden-closet encounters—until Adrian races to another woman’s bedside. Sophie assumes she’s his first love, only to discover she’s his sister…and Adrian has always wanted Sophie.
