After reading Dash's journal from the previous summer-the summer he doesn't remember-the kids piece together that Dash's new ghost girl friends were really puppets of a darker evil that collects the identities of its victims. And now that evil has come to call. Kelsey and Casey visited Black Sand Beach in the 90s, back when it was a legit beach town with boogie boards, ice cream, T-shirt shops. But they weren't on a summer escape. They were tagging along on their dad's monster-hunting mission. They found one. And it ate them. Now, back in the present, Dash and his crew must put this face-stealing monster to rest. Before the Darkness, and all the evil of Black Sand Beach takes Dash . . . forever.
