Jason Mason and the World's Most Powerful Itching Powder

Jason Mason is a pretty average kid. The kind of kid who doesn’t get chosen for the rugby team. The kind of kid who gets his lunchbox picked over by the school bully every day. The kind of kid who finds it hard to concentrate in class.

The kind of kid who is, actually, a SECRET AGENT.

WAIT . . . WHAT?

Jason is invited to take over from his recently deceased Great-uncle Bill to become a Secret Agent. His country needs him!

From being winched from a chopper onto the Beehive to meet the PM; to going undercover in a Mr Whippy van; to midfield at Eden Park, it’s all go for Jason Mason! His mission is to stop the arch-villain Hugh Jarse from sabotaging the Bledisloe Cup and taking over the world.

Has Jason Mason got what it takes to save the planet from evil?

You won’t believe the crazy, laugh-out-loud, risky, save-the-world type stuff this pretty average kid gets up to. This book is destined to leave you itching for more Jason Mason adventures!

The first title in an hilarious new illustrated junior fiction series by beloved Kiwi entertainer Jason Gunn and his brother and talented writer Andrew Gunn.

Uproariously funny and mega-action-packed, Jason Mason is the humble, relatable hero Kiwi kids have all been waiting for.


NZ Booklovers ~ “Written in that almost ubiquitous drawing slash text style aimed at young people from about 8 upwards, the level of writing certainly fits well in that upper primary, intermediate level of school – and it will clearly become a favourite amongst boys with its swashbuckling action, and cheekiness throughout. Even year 9s will get a kick out of the adventure component of the book. 
“One may even learn a thing or two about everything from geography to trigonometry as Jason Mason uses all kinds of theories and operations to solve the mystery of this powerful itching powder. 
“Everyone always wants to root for the hero, and Jason Mason is the exact type of Kiwi legend that our young people need in their lives. Quintessentially Kiwi, full of localised knowledge and strong references to te ao Māori, this feels timely, effective and highly engaging.”
