Brooklyn Briggs is a high school science teacher who has always been great with chemistry but terrible when it comes to relationships. When Jordan Torres, her brother Houston's best friend and the guy who drove her crazy in high school, offers to coach her into getting a date with her longtime crush, she knows she can't turn down the help.

But when she starts to develop feelings for Jordan, she is torn between risking their friendship and giving in to her heart. And despite warnings from his best friend, Jordan is drawn to Brooklyn in a way he's never been before and can't seem to remember that she's in love with someone else.

Brooklyn and Jordan must decide whether to take a chance on each other or stay in the safety of their friendship to protect Houston. But they can't deny perfect chemistry.
