The Sin Eaters

Civilization ended when living lightning became the world's apex predator. Hungry for modern technology, the lightning forced humanity to abandon its tools and return to a feudalism it hadn't experienced in 500 years.

The sickly boy Fen is born on the wind-blown Siberian Steppe of this stricken world. Gifted by a near-fatal childhood illness with a bristling armor of ragged bone and a powerful vision for how the world must be, he struggles to grow into a powerful chieftain in time to protect the Endless Tribes of his feral home from a threat his people thought had died two centuries before.

The Hollow Folk - the hidden remnant civilization that all who know the way of things know helped ruin the world - have returned to finish ravaging the surface of the earth.

Two long centuries before Fen is born, in the modern world we call home, a lonely woman named Eliza sits slumped in the ruins of her career. Tempted by sheer curiosity and a moonshot at professional redemption, she follows the mysterious Grupo de Pachakuti to the Andean peaks where she meets a man who could not be less, or more, human: Charlie.

Eliza is drawn into the depths of this impossible man's hallucinations of Norse colonies, Aztec sacrifice, and his suicidal need to escape the planet or die trying.

Eliza, Fen, and Charlie finds their lives woven together by time, change, and lightning as their worlds begin to end in The Sin Eaters.
