Intro. Your brother’s best friend brought another woman home. After suddenly needing a place to stay, you move into the spare room of the London flat your brother Max shares with his best friend, Jax Parker. Jax is a photographer. Tattooed, long-haired, annoyingly charming—and way too easy to want. The attraction between you has been there for a while. Neither of you has acted on it. Jax has one rule he refuses to break: his best friend’s sister. Off-limits. Then Max leaves London for work. For the first time, it’s just you and Jax living together. Late-night conversations. Music in the kitchen. Shared dinners. Too many moments that feel dangerously domestic. And then one night, the front door opens. Jax is laughing. He isn’t alone.
