What’s it about?

The story.

Daisy Thistledown's journey reaches its final stage in The Forest in the Sky. After discovering the Greenwild and travelling beyond the sea, Daisy and her friends must face the greatest threat yet to the wild magic they love. The adventure moves to a spectacular new realm, where sky, forest, danger, and hope are bound together. Pari Thomson's finale continues the trilogy's mix of page-turning fantasy and environmental imagination, giving young readers a magical story in which protecting nature is not background decoration but the heart of the quest. Elisa Paganelli's illustrations help sustain the series' lush visual identity, while the story brings together friendship, courage, discovery, and the responsibility of defending a living world. This is not a standalone entry point, but a giftable and satisfying conclusion for Greenwild readers.

Why it lands

Why they love it.

Why kids love it

The specific awe is the forest in the sky — Daisy's quest reaches its biggest, most spectacular setting, with floating woodlands and the final fight to protect the Greenwild's wild magic. A reader who's grown alongside the trilogy gets the conclusion they've been waiting for. Gift-worthy art throughout.

  • Going on a quest
  • Secret world
  • Magic powers
  • Making a difference
  • Friendship and belonging

Why parents love it

The Greenwild finale — the trilogy's biggest setting, the strongest environmental stakes, and the closing volume that makes the whole arc worth giving as a complete set. Not a starter; the satisfaction depends on the previous two. Pari Thomson's eco-fantasy lands cleanly.

  • Beautiful illustrations
  • Conversation starter
  • Great writing
  • Educational for adult too
