It is said that Lucifer was a fallen angel, cast out from a heaven too pure for his evil. But they are wrong. Lucifer was a god who delayed time until he gained his kingdom in hell. When Syd Rain finds herself on the bad side of the Unholy, she learns just how deep their connections are and how dark their sins are. She also learns that Lucifer is not who she thought he was. He's even worse. As she navigates Alexandria's history and her twisted connection to her brother, she discovers that not all secrets are meant to be shared, and that sometimes running away is far less cruel than fighting back.
