What’s it about?

The story.

The underworld is a dangerous place, full of fiery landscapes, marauding dragons and creatures you really wouldn't want to meet, but none of that bothers Demise. Better known as Bone Head, he's a skeleton guardian who is quite sure he's the best there has ever been, and he's desperate to prove it to Hades himself. When one of his attention-seeking schemes goes catastrophically wrong and takes out the gates of Hades' fortress, Bone Head and his long-suffering supervisor Mort are demoted to the worst job going: dog-sitting Cerberus, the famously ferocious three-headed hound. Written as Bone Head's own diary, with his boss Mort scribbling sarcastic corrections in green ink on every page, Jamie Gregory's fully illustrated debut is a riot of two-colour comic art, terrible decisions and Greek-myth mayhem. Fast, silly and packed with visual jokes, it's an ideal reluctant-reader adventure for fans of Bunny vs Monkey and Loki.

Why it lands

Why they love it.

Why kids love it

Bone Head is hilariously sure he's brilliant while getting everything wrong, and Mort's grumpy green scribbles all over his diary are laugh-out-loud funny. Dog-sitting a giant three-headed hell-hound goes exactly as badly as you'd hope, and the pictures are everywhere.

  • Trickery and cleverness
  • The underdog winning
  • Breaking the rules safely

Why parents love it

The diary-plus-annotations format and two-colour art on every page make this an easy win for reluctant readers, and it slips in real Greek myth alongside the chaos. A big, funny page-count that confident younger readers will race through.

  • Shared humour
  • Quick to read
  • Indie gem discovery
