An unsettled past . . .

Ten years ago, Stacy Buchanan's mother—the mayor—was found dead in Coldwater Cove, Maine. Her death was ruled an accident, but Stacy never got over the feeling that something was off. Her father's health takes a turn for the worse, and he can no longer live alone. A champion swimmer turned journalist, she is forced to pass up a dream job at ESPN to return to the cove. 

Former marine turned FBI agent Trent West has thought of nothing for the past ten years except his secret mission. Undercover as Trent Clark—a delivery man for Worldwide Parcel Service—he moves to the cove and befriends the Buchanans. 

After Stacy finds a key piece of evidence that proves her mother's death was no accident, the case gets reopened. She can't move on with her life or find closure until justice is served, but a desperate killer is still out there and will do anything to keep the truth buried in the past. 

The only person she trusts is Trent, who keeps turning up whenever she needs him. He offers to help her find the killer, but she discovers he has a few secrets of his own. Secrets that link him to her mother's case, making Stacy doubt everything she thought she knew and threaten her chance at finally being happy.
