The Secrets of Underhill

A young apprentice fights to save an ancient grove of magical trees in this page-turning fantasy adventure, perfect for middle grade fans of Kelly Barnhill and Jessica Townsend.

Nick Sixsmith has spent her whole life on the road. The daughter of a traveling arborist, she moves from town to town with her mother, caring for the ironwood groves that people rely upon for survival. When a dangerous blight threatens these magical trees, the Sixsmiths must journey to the city of Mistwood for answers.

Nick can’t wait to explore everything Mistwood has to offer: the bustling markets, the neighborhoods nestled behind a roaring waterfall, and the vast ancestral grove of ironwood trees. But dark secrets simmer beneath the surface as people start to disappear and tensions in the city reach a boiling point.

As the mystery grows, Nick and her new friends must follow the trail where it leads them--underground, to a strange and enchanting place called Underhill. Only there, among the roots of the ancestral grove, will Nick find a way to save the ironwood trees and the city she’s come to love.

This immersive fantasy adventure combines vivid world-building with timely themes of environmentalism, and young readers will be riveted until the final page.
