When a creature of the treetops listens to the song of a snake, she finds herself drawn into an adventure deep under the earth.
Witch-Hazel was never good at being a squirrel. She could never find her lost stashes of acorns, but maybe she can prove herself by finding a treasure that matters much more -- the lost Celestial Fragments of the All-Being. Witch-Hazel's quest takes her through labyrinths, lost mole cities, and underground kingdoms. She faces riddles from a leontaur, an army of ghost moles, and sorcerer crabs, but she also makes unexpected friends.
Can Witch-Hazel find the Celestial Fragments and make it back to the sunlight world above? If she survives, will she be the same squirrel who began her journey, or has she been forever changed by the snake's song?
