Justin Chase is having the WORST WEEK EVER! His Mum has just married a vampire. His Dad is driving a giant toilet on wheels. His cat has probably been abducted by aliens. A bully is making his first day at a new school miserable. And right now, he's hanging off the edge of a 10-metre-high diving tower in front of his entire class wearing nothing but rapidly disappearing crocheted swimmers!

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.
