Late one spring, Hallie Hartley learns she's inherited a beautiful old house on Nantucket from an ancestor she never knew she had. She learns of her luck from Jared Montgomery, who arranges for her to take on his cousin James Taggert as a private physical therapy client for the summer. Hallie expects a spoiled, frivolous playboy, but Jamie surprises her by being kind, considerate, and humble - not to mention incredibly strong and handsome. But Jamie's hiding something: every night Hallie hears him crying out in his sleep. Finding that only her presence can calm him, Hallie begins spending the night with Jamie, sneaking away every morning before he wakes up. It's not until Jamie's extended family descends onto the island to celebrate a lavish wedding that she discovers the truth: Jamie was a soldier, wounded in combat while saving a friend, and has suffered from PTSD since his return. Jamie withdraws, embarrassed by his vulnerability, while Hallie questions how she can trust him after he's lied to her all summer. But as the two team up to solve another of Nantucket's enchanting mysteries, whether it's the romantic island setting or possibly the work of some meddling matchmaker ghosts, Jamie begins to realize maybe he's found the one woman who can love him for who he is, scars and all.
