Have YOU ever had a bad week? Start Monday with a bang in the hilarious new series taking the world by storm. His mum just married a vampire, his dad is driving a giant toilet on wheels, and his cat’s been abducted by aliens (probably). Justin Chase is having the WORST WEEK EVER! And that’s all before he’s even started his first day at a brand-new school. At least he has the perfect chance to show off his prowess in the swimming pool, right? Maybe not... As right now, he's dangling off the edge of a 10-metre-high diving tower in front of his entire class wearing nothing but rapidly disappearing crocheted trunks! And it's only... MONDAY! The first book in the hilarious new seven-part highly-illustrated series for fans of the globally bestselling Treehouse series.
