Alterverse. The Age of Magic, #1

The forces of Chaos have defeated those of Order and recreated reality. The result is a dystopian multiverse ruled by the Dark Gods and policed by vampires who serve as their high priests. Into this Alterverse comes a heavensent African, gender-switching, interdimensional traveler who now finds himself permanently stuck in female form and tasked with the unenviable job of restoring reality. He/She must locate 17-year-old Alaric, son of the imprisoned witch Samantha Twitch and the banished demon Lucifer, and help him form a rebellion.
But in this altered reality familiar faces are not who they may seem and some who had died now still live. Pandora and Cody's teenaged children Quinn and Ursula join Alaric's nascent resistance alongside the demon Asmodeus, Grand Duke of Hell Eligos, Nitrate (an emotive from the Dreamscape), Kita the kitsune, and a Kunoichi (Japanese female assassin) against overwhelming odds, as they seek not merely to change the world but the entire multiverse, and overthrow the gods themselves.*** Book 8 in the Halos & Horns fantasy series *** Book 1 in The Age of Magic story arc ***
