“He fished in his pocket for his keys and instead pulled out the last geode, gray and smooth, earth-shaped. He held it, warming in his palm, thinking of all mysteries the world contained: layers of stone, concealed beneath the flesh of earth and grass; these dull rocks, with their glimmering hidden hearts.”

“he could feel the earth beneath, all the deep stone of it, cool and hard near the surface of the earth, but hotter and softer as you went deep, until it flowed like honey, a vast sweet fiery ocean of molten rock a thousand times more voluminous and ten thousand times heavier than the sea.

Someday he might be able to decipher the spell. That possibility would gently warm his heart from within.”
