"We thought of Persephone for a while in silence. I imagined her struggling her way toward us. She squeezed through black tunnels. She took wrong turns, banged her head against the rocks. Sometimes she gave up in despair and she just lay weeping in the pitch darkness. But she struggled on. She waded through icy underground streams. She fought through bedrock and clay and iron ore and coal, through fossils of ancient creatures, the skeletons of dinosaurs, the buried remains of ancient cities. She burrowed past the tangled roots of great trees. She was torn and bleeding but she kept telling herself to move onward and upward. She told herself that soon she'd see the light of the sun again and feel the warmth of the world again."
Skellig by David Almond
**Legend says that Persephone coming to the surface from the Underworld signals the arrival of Spring.
