The sequel, Darth Paper Strike Back, is just as good. Here's the booktalk:
Whenever there’s a force for good – Dwight and Origami Yoda – there’s also a force for evil. In this case, it’s Harvey. Seventh grade has barely started, and Harvey has already unleashed the power of the Dark Side, in the form of his own origami finger puppet: Darth Paper. Harvey’s made it his mission to bring Dwight down, and he’s quite obvious about it. His minion Darth Paper looks like Darth Vader, and even has own little pink lightsaber. In order to stop Harvey and to prevent Dwight from being sent to a school for really bad kids, Tommy and the others start a case file. But it may not be enough. Origami Yoda seems to be losing it. A popular girl named Jen (who believes in Origami Yoda) asked him for advice, and all Origami Yoda could tell her was, “Zero Hour comes. Prepare to meet your doom!” You could get kicked out of school for saying such things! Is Origami Yoda actually helping Harvey and Darth bring about his own downfall? Dwight’s friends are starting to wonder. Darth Paper Strikes Back: An Origami Yoda Book by Tom Angleberger.
