Public school teacher Cara Talarico is determined to pay off her student loans by the time she turns thirty-five and has sworn off everything fun to make it happen—including dating. Attending her high school reunion definitely ranks in the not-fun category. The last thing she expects is to reconnect with Lauren Havemayer, her unrequited crush from ten years ago.

Having just returned from Europe, Lauren barely remembers Cara from their school days but can't deny the sparks flying between them now. It's too bad Lauren is abstaining from romance—love has caused her nothing but pain and she doesn't trust herself or anyone else.

They embark on a cautious friendship with benefits—no feelings allowed. But with their chemistry off the charts no matter how much they try to fight it, feelings are being felt. They both agreed to the rules at the start, but keeping them is more complicated than it seems.
