Discover a stunning new children’s tale from the bestselling, Pulitzer-nominated

author of Heroes of the Frontier and What Is the

What.

When things fall down, who lifts them up?

What if the ground beneath your feet was not made of solid earth

and stone but had been hollowed into hundreds of tunnels and passageways?

What if there were mysterious forces in these tunnels, mere

inches below you as you sit in class or eat a banana?

What if it were up to just two kids to stop these forces? What would

it feel like to know the fate of an entire town rested on your

shoulders?

Twelve-year-old Gran Flowerpetal is about to find out.

When Gran’s friend, the difficult-to-impress Catalina Catalan, presses

a silver handle into a hillside and opens a doorway to underground,

he knows that she is extraordinary and brave, and that he

will have no choice but to follow her, and help her save the town

(and the known world). With luck on their side, and some discarded

hockey sticks for good measure, they might just emerge as heroes.
