Book 16: The Strange Case of Origami Yoda by Tom Angleberger
A little Diary of a Wimpy Kid, but told through various "case file" entries, this middle school novel is a cute, fun, fast read. Tommy is trying to figure out whether the origami Yoda that his friend Dwight has created can really dispense useful and real advice. Dwight pulls out the origami Yoda finger puppet and in his best Yoda voice provides answers to his fellow middle schoolers' questions, with mostly positive results. Tommy has everyone who asked for origami Yoda's advice to record their experience, and he and Harvey, who doesn't believe in Yoda, comment on the entries. In the end, will Tommy end up believing or not?
