. Darby and Morgan haven’t spoken for two years, and their friend group has splintered. But when the body of their former science teacher is found in the marsh where they attended camp that summer, they realize they have more questions than answers . . . and even fewer memories. The group of reunited friends suspects that a murderer is stalking the coastal highway 30A, and they are desperate to recover their memories as quickly as possible . . . before their history they can’t remember repeats itself. As tensions rise and time runs out, Darby and Morgan begin to wonder if they can believe one another . . . or if they can even trust themselves.
