What’s it about?
The story.
Daisy Thistledown is searching for her missing mother when she discovers a hidden doorway into the Greenwild, a magical world where plants, people, and impossible natural wonders are bound together. Inside this secret realm she finds danger, friendship, botanical magic, and the possibility that her mother's disappearance is connected to something far bigger than she imagined. With help from other young adventurers and a memorable cat, Daisy must learn who to trust and how to protect a world many people do not even know exists. Pari Thomson's opening Greenwild novel combines the classic thrill of a secret world with a contemporary environmental edge, while Elisa Paganelli's illustrations help give the story a lush, inviting feel. It is magical, page-turning, and emotionally accessible without being lightweight.

In the classroom
How it works in school.
A lush, eco-magical adventure series — a great class read-aloud and a companion for environment and nature themes.
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 kick is the door itself — Daisy stepping through an ordinary-looking gap into a wild magical world, the way a nine-year-old reading it suddenly wants to believe their own back garden might do the same. The eco-fantasy that gives the secret-doorway trope its best modern outing.

Why parents love it
The eco-fantasy series for a child who loved His Dark Materials but isn't quite ready for it — Thomson's secret botanical world, a missing-mother quest, illustrated chapters that hold a young reader. The Greenwild opener earned its early-trilogy comparisons; the next two volumes deliver. Strong gift for a magical-thinking nine-year-old.
- Beautiful illustrations
- Conversation starter
- Great writing
- Educational for adult too
