Brain Camp by Susan Kim and Laurence Klavan
This is a very atmospheric book. The muted color palate suits the story’s tone, as does Faith Erin Hicks’ illustration style. Make no bones about it, this is an odd story, something along the lines of mild horror. It is a bit graphic in a few scenes with mild blood, but not terribly so. It’s solidly plotted and characterized with a nice, slightly open ending.
