From two-time Mary Higgins Clark Award-winning author Carol Goodman comes a new mystery, about a group of friends isolated on a remote island with a history of foul play.

Lucy Harper still has traumatic memories and lingering health problems from the 2020 pandemic. So, when a new virus surfaces years later, she and her husband, Reed, seek refuge on his family's private island off the coast of Maine. Ostensibly safely sequestered with their five closest friends and family, Lucy should feel at ease. So why does she feel the weight of the island's dark history pushing down on the group?

As Lucy uncovers Reed's family secrets and the island's history as a quarantine hospital for typhus patients, she becomes obsessed with the past and feels her own grip on reality slipping. Tempers flare, strange signs appear in the woods, and accidents turn deadly. Is the island haunted by the dead? Or is someone amongst the living taking their revenge?
