It's a new year at Wayside School, and Mrs Jewls's class on the thirtieth floor has a LOT to deal with. First of all, they must prepare to face The Ultimate Test, which involves a fiendishly difficult Spelling Bee, upside-down singing and blindfolded smelling. Meanwhile the paperclips are triple-locked in a safe so no one can access them, Miss Mush is threatening to serve rainbow stew for lunch – and a CLOUD OF DOOM is gathering over the school. It can only mean one thing … the kids at Wayside School are in for their strangest year yet!

From the basement to the thirtieth floor, Wayside is packed with quirky and hilarious characters who are all brought to life in this brand-new instalment of Louis Sachar's much-loved Wayside School series. With brilliant illustrations throughout, this is an unmissable, irrepressible story of mixed-up mayhem from the bestselling author of Holes.
