Kira Kallis is newly thirty, tired of being single, and wants to find someone special in time for Valentine's Day. After spending years focusing on her career, she has a great job, and supportive family and friends, but life as the perpetual third wheel is lonely. Creating an online dating profile was the easy part. Navigating the lines between truth and illusion in her matches is a lot harder.

Hunter York has been friends with Kira for years. From morning runs to chats over coffee at the office, he loves the time they spend together. But it can't go further than that. She's his best friend's sister, his co-worker, and off-limits for too many reasons. When he learns that she's using a dating site, he insists on checking into her matches who draw too many questions and yield not nearly enough answers. Overprotective or not, he cares too much to risk anything happening to her.

The more time they spend together, the harder it is to deny their connection and chemistry. Kira begins to wonder if the perfect match could have been by her side all along, and Hunter struggles with what could happen if he discards all the reasons he's wrong for her. But taking that step means going beyond paper hearts and chocolate-flavored kisses. It means risking a friendship they've both grown to depend on.
