Lisa Hawley is perfectly satisfied living on her own. Having fully recovered from a brutal divorce nearly two decades earlier, she has successfully raised her kids, Juliet and Theo, seeing them off to college and beyond. As the owner of a popular boutique on Nantucket, she's built a fulfilling life for herself on the island where she grew up. With her beloved house in desperate need of repair, Lisa calls on Mack Whitney, a friendly--and very handsome--local contractor and fellow single parent, to do the work. The two begin to grow close, and Lisa is stunned to realize that she might be willing to open up again after all . . . despite the fact that Mack is ten years her junior.

Juliet and Theo worry that Mack will only break their mother's heart--and they can't bear to see her hurt again. Both stuck in ruts of their own, they each hope that a summer on Nantucket will provide them with the clarity they've been searching for. When handsome entrepreneur Ryder Hastings moves to the island to expand his environmental nonprofit, Juliet, an MIT-educated web designer, feels an immediate attraction, one her rocky love life history pushes her to deny at first. Meanwhile, free spirit Theo finds his California bliss comes to a brutal halt when a surfing injury forces him back to the East Coast. Upon his return, he has eyes only for Mack's daughter, Beth, to whom he is bound by an unspeakable tragedy from high school. Can they overcome their past?

As the season unfolds, a storm threatens to shatter the peace of the golden island, forcing Lisa, Juliet, and Theo to decide whether their summer romances are destined for something more profound. Nancy Thayer dazzles again in this delightful tale of family, a reminder that sometimes, finding our way back home can bring us unexpected gifts.
