Mr. Wrong Number

Olivia Marshall has always been the family screw-up, and a string of bad luck has done nothing to change that reputation. So when an accidental text from a stranger spirals into the most electric, honest connection she's ever had — completely anonymous, completely addictive — it feels like finally catching a break. What she doesn't know is that the man on the other end of those messages is Colin Beck, her older brother's infuriatingly attractive roommate, who has always seen her as off-limits. The closer they get in real life, the more complicated those late-night texts become.

Lynn Painter writes rom-com dialogue that crackles — the banter is fast, the tension is earned, and the comedic timing lands consistently without undercutting the emotional beats. What makes this one work on the page is how Painter balances two distinct relationship threads (the anonymous texts versus the charged in-person dynamic) without letting either feel thin. The dual-track structure builds genuine dramatic irony, so readers feel the slow-burn collision coming long before the characters do. It's a quick read that doesn't feel slight.
