Newly turned thirty, Cameron North is preparing himself to spend his life alone. When he inherits his great-aunt's teashop on the remote island of Farlough, he returns for the first time in more than a dozen years to a place where memories—and demons—flit close to the surface of his mind. There he meets Gwyneth, a sassy barista who becomes his instant best friend—until Cam discovers she's the wife of his first love, Matthias. She has only the best of intentions when she arranges a reunion between the two men, and it forces them to finally discuss why Cam left the island so long ago. With his heart broken anew, Cam retreats to his great-aunt's house—where he learns he is not alone. Someone—or something—has pledged an oath to look out for Cam, and as he investigates the presence, he uncovers wounds that both he and his mysterious guardian sought to escape by coming to Farlough. Now Cam must figure out how to heal them—and himself.
