Ten years ago, a teenage summer camper disappeared while searching for a rumored treasure on a remote island. Now, the long-buried truth of what happened to her and the long-lost gold threatens the lives of her friends in this thriller from the critically acclaimed author of The Chateau.

Ten years ago, a group of American teenage summer campers went to a lush and isolated Azores island for a hiking and heritage trip. But when a clue to a local legend of buried treasure emerged, the summer devolved into a frenzied hunt and culminated in the disappearance—and rumored murder—of “it girl” camper, Sydney. She was never seen again and the treasure never found.

Now, a decade later, Sydney’s closest circle returns to honor her memory: Sydney’s sister and fellow camper, Olivia; a group of childhood camp friends; and their beloved counselors. They’ve all agreed to participate in a documentary probing what really happened to Sydney.

The group reunites in paradise and retraces their old haunts, hiking along crater lakes and submerging in thermal hot springs. But not everyone has innocent motives for returning to the island. And when the documentary filming reveals explosive truths and fresh hints resurrect the tantalizing treasure hunt, the group begins to implode. Old feuds reignite—and then one of them turns up dead.

Which means that a murderer has surfaced...again.
