The Abyss swallows those the noble houses discard. Bastard children, failed heirs, inconvenient truths—the endless pit beneath the world takes them all, and no one climbs back out. No one, that is, until the darkness itself offers a bargain.

Lucia, illegitimate daughter of the House of Lordvel, meets the Evil God in the depths and strikes a pact written in something darker than blood. Revenge. Rebirth. A second chance. She wakes ten years in the past, before the betrayal that cast her down, before her family turned their backs. But power borrowed from the Abyss comes with strings, and the god who saved her might not let her walk away clean. Can she rewrite her fate and reclaim what was stolen, or will the price of vengeance consume the very family she once wanted?
