During an ancient battlefield campaign, military doctor Sage Sterling used reverse life witchcraft to save the dying general Kai Sawyer. The spell backfired, trapping Kai Sawyer in the Reincarnation Cycle marked with a flaming blood seal, doomed to repeated short, violent deaths, while Sage Sterling was cursed with eternal immortality. For eight hundred years, she has repeatedly found his reincarnated selves, only to be stuck in a fatal deadlock: every time they recognize each other, he will die a violent death. When the broken hairpin from eight hundred years ago is reunited, Sage Sterling chooses to stop fleeing, face the reincarnation killing curse head-on, break the deadlock and guard the redemptive fate spanning a thousand years for the two of them.
