This is not just any summer camp for teenagers: this is a summer camp for teenagers suffering from mental illnesses, sort of The Breakfast Club with trees. Zander’s not saying why she’s there, and she seems perplexed that the other campers, whom she initially dismisses as “crazy,” will — except for “Alex Trebek,” whose every English word is a lie. (Not so sure about Bek’s French.) Zander ends up having to juggle two emotions at once: her growing interest in a boy named Grover Cleveland, and her concern for her seriously bipolar cabinmate Cassie. Not even Maslow’s hierarchy of needs can help her at this point. I’m not entirely sure the teens’ various ailments are described in a way that the American Psychological Association would approve, but life is like that. A cut above standard YA fare.
