What’s it about?

The story.

Ten years ago the land of Skree was conquered by Gnag the Nameless and his reptilian Fangs of Dang, and now the Igiby children — sensible Janner, reckless Tink and lame little Leeli with her dog Nugget — live quiet, watchful lives in the seaside town of Glipwood. Then Tink lifts a hidden map marked “The Jewels of Anniera”, and the family is pitched into a headlong adventure of toothy cows, sea dragons, a mad ex-pirate grandfather and a secret that will change everything they believe about who they are. Andrew Peterson's series opener is a big-hearted, footnote-strewn fantasy that mixes genuine danger with laugh-out-loud invention and a deep vein of family love. Illustrated throughout by Joe Sutphin, it's a read-aloud treasure and a gateway to one of the most warmly regarded fantasy sagas for middle-grade readers.

Why it lands

Why they love it.

Why kids love it

The Igiby kids feel real — bickering, brave and out of their depth — and the world is stuffed with toothy cows, sea dragons and villainous lizard-men. The footnotes are funny, the danger is genuine, and the mystery of who the children really are keeps you turning pages.

  • Being special or chosen
  • Going on a quest
  • Adventure and freedom
  • Family belonging
  • Surviving danger

Why parents love it

Peterson writes with wit and warmth, layering laugh-out-loud footnotes over a story about a family holding together under threat. It reads aloud beautifully, rewards attention, and opens a saga that grows richer and deeper with every book.

  • Great writing
  • Shared humour
  • Conversation starter
