The Dream Spies (Nightmare Thief, 2)

Maren's life has finally gone back to normal. Her sister, Hallie, is recovering from her coma, she's still allowed to work in her family's dream shop, and there's been no sign of Obscura, the evil nightmare thief. But when Lishta, Maren's grandmother, finds an ad for a sleepaway camp designed for dreamers, alarm bells start to ring. Lishta's never heard of these camp directors, which worries her, and prompts Maren to begin an investigation. Almost right away something seems terribly off. Campers awake humming the same song, a whole bunk of girls does their hair the exact same way, and everyone seems to be having identical dreams. Things quickly go from bad to worse when Maren discovers that most of the campers are chronic sleepwalkers. Maren will have to uncover who's really responsible for this camp, and stop them from turning more dreamers into sleepwalking zombies, before it's too late!
