Eden Hills, Minnesota, is famous for two things: its lucrative, '80s-inspired fashion mall, and a missing-persons epidemic that has plagued the town's youth and confounded officials for years. High school junior Penny has grown skeptical of the town's official stance on the disappearances but has so far kept that to herself. See, she just started her first-ever job at one of the mall's trendiest stores and doesn't want to sound like a conspiracy nut to her cool friends and the popular guy who might just help her get over the dream girl who broke her heart. But when a late-night party in the mall turns deadly, Penny won't have the luxury of playing it cool. A killer is on the loose, and the dark history of Eden Hills is about to be revealed.
