The humor of Captain Underpants meets the blockbuster format of Diary of a Wimpy Kid in this laugh-out-loud series about Justin Chase, who is having the Worst. Week. EVER!

Have you ever had a bad week? Justin Chase sure has and THIS is it!

His mom 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 30-foot-tall diving board in front of his entire class wearing nothing but rapidly disappearing crocheted swim trunks!

And it's only...MONDAY!

The first book in the new laugh-out-loud hilarious seven-part middle-grade book series based loosely off this husband and wife team’s own family!
