Before his disappearance, the mad locksmith Avery Guissant completed his masterpiece—an inscrutable clockwork mechanism known only as the Ouroboros Lock. Said to open the gates of time itself, the lock has become the most coveted occult artifact in the City of Dreadful Night. Now, three men seek to claim its power in a bloody feud. One struggles to recover his stolen heirloom, another kills to serve his lord’s avarice whim, and a third labors to master the lock’s time-twisting magic. Three tales, intertwined through time and space. Three schemes, murderous and diabolical. Three souls, locked in conflict and damned by the Fates, their doom ordained by the Ouroboros Lock.
