McKenna Williams doesn't like staying in one place. She has a restless soul, which has served her well for the last twenty-three years. Right now, her soul is taking a little pit stop in the town of Castleton, Maine, for the summer, and she's enjoying the ocean breezes and friendly people. Plus, the house she's staying in is right next door to her sister, Julia. She's determined to let nothing mess up her zen, until she gets a request to teach a private yoga class for recent divorcee, Piper Patrick, and she's hit with an instant attraction so intense, she can barely breathe. Piper is beyond off-limits: Not only is she McKenna's client, she's just ended her marriage, she has a son, and there's nearly a 10 year age gap between them. Everything about falling for Piper is a bad idea. The magnetic pull toward each other is undeniable, and McKenna knows that it can only end in heartbreak. Will she take a chance on the woman she can't resist? Or will she cut and run to save herself from losing it all?
