Samantha Parker has the perfect life--a loving husband, three wonderful kids and a comfortable suburban lifestyle. But on the brink of their long-awaited empty-nest chapter, Will asks Samantha for something she never dreamed of: an open marriage. Desperate to keep her husband happy, Samantha proposes a summerlong separation with no contact. She knows she has to use the opportunity to find herself, but she also has no interest in being with anyone but Will. She's confident when the season is over, they'll get back together like this time never happened.

Then Sam gets an adventurous offer from Will's best friend, Logan Martin, a classic-car restorer. Logan and Sam haven't had an easy relationship, but prickly Logan needs help driving across North America making deliveries. Among the winding roads and breathtaking backdrops, everything Sam thought about life is challenged--even her new connection with Logan.

But when summer closes, Sam has to decide: Will she go home to the familiar stability of her past...or choose the thrilling uncertainty of her future?
