Wilson spins six worrisome personal or family concerns anonymously posted to a classroom discussion board into light-toned (by and large) first-person short stories. The tales are interlinked: Holly is furious at the prospect of a stepmother who’s actually lovable; shy Greg is mad for Holly; William is fussed that he’s at the bottom of the class in everything; Natasha has a yen to be in the class talent show despite severe physical disabilities. Twelve-year-old Lauren Roberts, winner of an online contest run by Wilson, provides a seventh heartrending contribution. In it, a hyperactive, reasonably wise teacher named Mr. Speed, plus other well-meaning adults and peers, provide no easy answers in a drama about domestic violence, but do help all these children toward at least momentary triumphs—often in an ingenious fashion. A lively gallery of mostly likable characters, presented through an open-ended premise that, to judge from the 15,000 contest entries Wilson received, shows plenty of potential for turning young readers into young writers.
