What’s it about?

The story.

Ash lives in a tiny stronghold at the edge of the known world, cut off by the dangerous Snow Sea and the leviathans that lurk beneath it. He is waiting for his parents to return, watched over by Tobu, his grumpy yeti guardian, and trying to hide the strange song power that makes other people fear him. When the Frostheart, a mighty sleigh-ship full of misfits, arrives, Ash finally has a chance to search for answers. Jamie Littler's debut novel is packed with black-and-white illustrations, jokes, action and big-hearted fantasy. It has the pace and humour to pull in reluctant readers, but the emotional hook is strong too: Ash wants family, belonging and the truth about who he is. Frostheart is the clear entry point to the trilogy.

How it works in school.

A thrilling, warm-hearted fantasy-adventure series — a great class read-aloud and reluctant-reader pick about belonging and found family.

Classroom role

  • Classroom library
  • Read aloud
  • Discussion and empathy

A book children love that happens to support school — never a stand-in for the texts a class is taught with. Reviewed for the classroom · June 2026.

Why it lands

Why they love it.

Why kids love it

The specific premise is irresistible — Ash lives in a frozen world where singing wakes the monsters below the snow, and he is supposed to be quiet. He isn't. A nine-year-old reading it gets the satisfying setup of a hero with a power that's also a problem, and the heavily-illustrated pages turn fast.

  • Going on a quest
  • Secret skill
  • Adventure and freedom
  • Friendship and belonging
  • Animal companions

Why parents love it

The illustrated middle-grade fantasy for a child ready to move beyond Wimpy Kid format but not quite into pure prose. Jamie Littler's Phoenix-Comic background shows in the density of art; the trilogy works as a complete world for an eight-to-eleven-year-old. The bridge between funny graphics and serious fantasy.

  • Shared humour
  • Quick to read
  • Conversation starter

Jamie Littler

Writer & illustrator · United Kingdom

Jamie Littler is a British author-illustrator best known for the Frostheart middle-grade fantasy-adventure series, illustrated chapter books about a young Snow Sea pathfinder and his eccentric crew, set in a Scandinavian-folk-fantasy world of ice, song-magic and monstrous Leviathans. Littler's voice is warm, generous and read-aloud-ready, with strong character work and the heart-on-sleeve register of a generationally Pixar-shaped storyteller.

A reliable middle-grade fantasy author for ages 8–11, particularly for fans of How to Train Your Dragon-style adventure.
