Have YOU ever had a bad week? The hilarious new series taking the world by storm.

His cat has been abducted by aliens, his dad is dating his new head teacher, and he’s unexpectedly gone viral online in the most embarrassing way. Justin Chase is having the WORST WEEK EVER!

At least his new-found inter-fame (or inter-shame) won’t stand in the way of getting the perfect school photo, right? Maybe not… As the school’s Super Science Spectacular is destined to blow up into a hair-raising, teeth-shattering disaster of epic proportions!

He barely made it through Monday, but now it’s… Tuesday!

The second book in the hilarious new seven-part highly-illustrated series for fans of the globally bestselling Treehouse series.
