Zephyr is the last human fighting evil in a world abandoned by the gods. When he is killed in battle by Tartarus, the god of destruction, all hope for humanity seems lost. But Zephyr’s fate is not sealed — the gods who find his battles entertaining have gifted him a second chance at life, as he is sent ten years into the past, back to when he was a slave instead of the most powerful human alive. Can Zephyr get his revenge against Tartarus and save the woman he loves, or is he doomed to repeat the past?
