What’s it about?

The story.

After one prank too many, the trickster god Loki has been banished to Midgard (that's Earth) to live as an ordinary, weedy eleven-year-old boy. Odin's deal is simple: show real moral improvement within a month, or spend eternity in a pit of angry snakes. To keep score, Odin hands Loki a magical, judgemental diary that forces him to confess the truth, even when the truth is as ugly as a naked mole rat. Worse still, Loki has to survive school and put up with an equally eleven-year-old Thor tagging along and making him look good by comparison. Told entirely through Loki's grumbling diary entries, doodles and comic strips, Louie Stowell's first outing as both author and illustrator is a wry, irreverent and very funny introduction to Norse mythology. Perfect for readers who love Diary of a Wimpy Kid and Tom Gates, it cheers on the bad guy while quietly asking what being good really means.

Fit check

Right for your child?

Where it lands by age

Aimed squarely at 8-11s reading independently, with the heavily illustrated diary format carrying confident readers from about 7. The comedy and short entries make it an easy, funny read-aloud, though it's built for solo giggling rather than a calm bedtime.

Why it lands

Why they love it.

Why kids love it

Loki is a genuinely bad god forced to be an ordinary schoolkid, and his outraged diary entries and rude doodles about Thor, teachers and mortals are hilarious. The magic diary that catches every lie means the jokes and the trouble never stop.

  • Trickery and cleverness
  • Breaking the rules safely
  • Magic powers
  • Being understood finally
  • Proving yourself

Why parents love it

It reads like pure comedy but sneaks in real Norse mythology and a sly question about what goodness means. The diary-and-doodle format pulls in reluctant readers, and the voice is sharp enough that reading it aloud is a genuine pleasure.

  • Shared humour
  • Quick to read
