Last Seen on Nantucket

When thirty-two-year-old Katie Chapman vanishes during an early morning run, Nantucket detectives Tina Fisch and Rick Caton suspect a shocking but isolated abduction on an island that prides itself on safety and discretion. It isn't isolated. It isn't random. She was chosen. For Rick, the case is personal. After solving the suspicious death of a close family friend the previous fall, he left the FBI and returned to Nantucket-and to the police department that forced him out a decade earlier.
As the investigation unfolds, the detectives uncover disturbing clues pointing to something far more sinister than a random crime. Beneath Nantucket's postcard-perfect façade lies a ritual that has quietly claimed victims for nearly four decades. And Katie may be next. People have disappeared before. Always quietly. Always without resolution. Katie is still alive-but running out of time. And what she's learning in captivity may be more dangerous than her captor realizes.
Now past and present are colliding, and Tina and Rick must find a man who has walked these streets for forty years-quietly devoted, utterly certain, and completely invisible. Because on Nantucket, the most dangerous man isn't the one consumed by darkness. It's the one who believes, with complete sincerity, that he is made of light. Last Seen on Nantucket is a gripping, atmospheric thriller perfect for fans of Harlan Coben, Riley Sager, and Lisa Jewell.
