Wally and Bez have spent the last six months eluding the Collective together. Not that the mages have spent much time pursuing the dangerous devil and his misfit mage, since even the best magics can't match a Diabolic's strength.

When Bez surprises Wally with an anniversary trip to a special event hosted by the Fae, Wally is presented with a chance to work on rare artifacts belonging to a Fae noble. However, Bez learns the Fae may be connected to the recent abductions of fellow demons, allowing them to crossover into various Hell dimensions—and threatening to expose his secret.

Bez is not the unstoppable devil that everyone believes he is. If the Collective learns about Bez's deceit, they will rain down the full force of their magical resources to kill him. Wally and Bez will need to work together to unravel the mystery behind the missing demons and study intricate dimensional magics all while traveling in a magical villa through space and time.

No longer haunted by the loss of Finn, Dorian's finally moving forward with his life and finding happiness at Milo's side. All he wants to do as his students move into their second year at the academy is prepare them for the industry and build a future with Milo.

Unfortunately, a stray piece of magic has sprung to life with plans of his own. This rogue manifestation has access to Dorian's power and his memories, and he intends on using that knowledge to steal Dorian's happy ending. Believing himself the superior half of Dorian, he's done the unspeakable, harboring Finn and the devil that nearly destroyed the city. Now, he's plotting to bring down the witch who failed to master his magics, failed to save Finn, and failed to embrace Milo while lost in grief.

The manifestation doesn't care who pays the price of blood, so long as he claims Dorian's body as his own. He'll stop at nothing to achieve a perfect future with Finn and Milo.
