There has been a terrible mistake. Instead of having thirty classrooms side by side, Wayside School is thirty storeys high! (The builder said he was sorry.) Perhaps that's why all sorts of strange and unusual things keep happening – especially in Mrs Jewls's classroom on the very top floor. There's the terrifying Mrs Gorf, who gets an unusually fruity comeuppance; Terrible Todd, who always gets sent home early; and Mauricia, who has a strange ice-cream addiction. Meanwhile, John can only read upside down, and Leslie is determined to sell her own toes. From top to bottom, Wayside is packed with quirky and hilarious characters who are all brought to life in this new edition with delightful illustrations by Aleksei Bitskoff throughout. This is an unmissable, irrepressible story of mixed-up mayhem from Louis Sachar, the bestselling author of Holes.
