What’s it about?

The story.

The trickster god Loki is still stuck as a peevish eleven-year-old, and now he has to work out whether he's the hero or the villain, both in his school play and in his mortal life. When Thor and Loki's 'parents' clear off on holiday, Odin sends Balder, Thor's insufferably wonderful half-brother and the god of making Loki look bad, to babysit. Naturally Thor is cast as the noble prince in the play while Loki is stuck as the villain, despite his obvious acting genius (it's basically lying, after all). Then Loki finds a cool ring that looks suspiciously like the cursed ring of Andvari. When he wears it everyone adores him the way they adore Balder, and a new voice starts whispering that he should give in to his deepest, darkest desires. What, Loki wonders, is the point of being good if everyone's already decided you're bad? Drama, doodles and hilarity abound in a myth-soaked diary comedy for fans of Diary of a Wimpy Kid.

Fit check

Right for your child?

Where it lands by age

Pitched at 8-11s reading independently, with heavy illustration supporting confident readers from about 7. The comedy carries well aloud, and the hero-or-villain thread gives older readers something to chew on beyond the jokes.

Why it lands

Why they love it.

Why kids love it

A cursed ring, a school play Loki is desperate to win, and a sneaky voice egging him on to be bad make this the funniest, most tempting adventure yet. Watching Loki wrestle with whether to just embrace being a villain is brilliantly relatable chaos.

  • Trickery and cleverness
  • Magic powers
  • Being understood finally
  • Proving yourself
  • Having a nemesis

Why parents love it

Under the doodles and gags is a genuinely thoughtful question about labels and self-fulfilling prophecies, as Loki asks why he should be good if everyone's decided he's bad. It's funny to read aloud and easy to hand to a reluctant reader.

  • Shared humour
  • Quick to read

About the author & illustrator

Louie Stowell.

LS

Louie Stowell

Writer & illustrator · United Kingdom · b. 1978

Louie Stowell is a British author-illustrator born in London in 1978, best known for the Loki: A Bad God's Guide series. After years writing non-fiction about space, ancient Egypt and science at Usborne and Ladybird, she made her debut as both author and illustrator with a wry, irreverent comedy in which the trickster god Loki is banished to Earth as a weedy eleven-year-old and given a magical, truth-telling diary and one month to prove he can be good. Told in grumbling diary entries and comic-strip doodles, the books blend real Norse mythology with poop jokes, boasts and genuine lessons about honesty, jealousy and owning your mistakes. The first title won Best Overall Children's Book at the 2023 British Book Awards. Perfect for fans of Diary of a Wimpy Kid who like a bad guy at the centre of the chaos.
