Forgotten Ghosts: Vesik, Book 8

Damian shouldn't have told himself things couldn't get any worse. They did. As Nixie struggles to unite the water witches, the Fae king discovers a spy in his ranks. Damian and his friends are forced to split their focus and their powers between the unrest in Faerie and the rising tensions in Falias. When Nudd's latest gambit puts humanity’s most dangerous weapons into his hands, they can't let anything stand in their way. They'll need help from new contacts and trusted allies if they hope to stop the Fae king's madness.

But the award for worst timing in history goes to an old friend: Vicky.
