Grandpa Is a Secret Supervillain : Old Habits Die Hard (and Explode)

This audiobook is narrated by a digital voice.

A retired supervillain. A washed-up hero. And a grandson who just wanted a quiet Tuesday.

When twelve-year-old Shaun discovers that his forgetful, cardigan-wearing Grandpa Joe was secretly the world-renowned Doctor Disaster, his life takes a sharp turn into the absurd.

Grandpa's secret underground lair is waking up, and the city of Maplewood is under siege by rogue breakfast appliances and jetpack-wearing pigeons. Alongside his Grandpa and the legendary (but extremely creaky) Captain Thunderstrike, Shaun must navigate a world of high-tech chaos and sentient glitter to stop a 'Sugar Bomb' from leveling the city.

Grandpa Is a Secret Supervillain is a hilarious, fast-paced adventure for fans of The Incredibles and Captain Underpants. It explores the messy, explosive, and ultimately heartwarming bond between a boy and the most dangerous man in a brown cardigan.

Themes: Intergenerational relationships, STEM-humor, superhero parodies, and family secrets.
