Child psychologist Gwen Traynor has learned the hard way that "perfect" men aren't always what they seem. After being dumped the night before her wedding, she's understandably wary of diving back into the dating pool. But when she meets Alex Coughlin, she's convinced her luck is changing. He's smart, handsome, funny—an ideal rebound guy. She doesn't intend to fall in love with him, but scintillating dates and mind-blowing physical chemistry have a way of winning a girl over. Just as things are heating up with Alex, Gwen meets her newest patient—a precocious preschooler whose chaotic soap opera-actress of a mother, Harmony, sounds an awful lot like one of Alex's crazy ex-girlfriends. Mostly because she is one of Alex's crazy ex-girlfriends. Unfortunately for Gwen, Harmony has a secret that plunges them all into a real-life daytime drama, complete with sex, lies, and Vegas elopements. With Harmony determined to reunite with Alex and Gwen's ex-fiancé begging for a second chance, only one thing is certain: new loves and old flames are an explosive combination.
