The summer we forgot : a novel
(Book)

Told in alternating voices, Darby, her ex-boyfriend Morgan, and their friends become embroiled in a murder investigation when their science teacher's body is discovered at the summer camp they all attended.

Darby and Morgan's friend group splintered two years ago. 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 begins to suspect that a murderer is stalking Florida coastal highway 30A, and they must try to recover their memories as quickly as possible-- before the history they can't remember repeats itself. As tensions rise, Darby and Morgan begin to wonder if they can believe one another-- or themselves. -- adapted from jacket
