School is out for the summer, and the Dunderheads are finally rid of the awful Miss Breakbone. Or so they thought! Teen star Ashley Throbb-Hart is shooting a movie nearby, and who should show up as an extra but their formidable former teacher! She's not the only Breakbone on the scene, either; after a string of burglaries strikes the town, Miss Breakbone steers her barrel-chested brother, Police Chief Breakbone, toward those meddling, good-for-nothing Dunderheads. And when Spider ends up in the wrong place at the wrong time, the blowhard chief has all the evidence he needs to lock him up. Can Einstein, Wheels, Nails, Spitball, Google-Eyes, Clips, Junkyard, Pencil, and Hollywood combine their talents to catch the real criminal before they join their friend behind bars? Newbery Medalist Paul Fleischman and illustrator David Roberts reunite for a delightfully triumphant sequel to The Dunderheads.
