Caves Beneath the Hollow: Book Six of Whispers in the Pines (Paperback) (ISBN-13: 9798299220254)

Beneath the Hollow lies a nightmare waiting to rise.

When the ground splits and water vanishes, Scout, Tuck, and Misty descend into the caves below their home-where the Devourer, a beast of endless hunger, stirs in the dark. Alongside their bold new ally, Pip the skunk, they must battle collapsing tunnels, bone-choked chambers, and the terror of being buried alive.

To save the Hollow, survival isn't enough. They'll have to trap the Devourer beneath the earth-no matter the cost.
