Incubus, Volume 6 (Light Novel‪)‬

GOING ON THE ATTACK
After the attack on his life is thwarted, Anthony decides to deal with Custodes Daemonium once and for all. Everything began with them. They were the ones who sent Brianna after him, forcing him to embrace his true nature as the world’s only Incubus, and while part of him was grateful because it gave him a wonderful bondmate, that didn’t mean he planned to let them enslave him.
Fortunately, Custodes Daemonium is currently fighting a civil war. Trinity, leader of the War Maidens and the moderate faction that wants to ally with Anthony, is battling against Chloe and Hendricks - a pair of warhawks who want to enslave him.
The choice of who to side with is clear.
But to reach Trinity and aid her, Anthony must first travel to New Denver, where they will have to face off against Dr. Elena Vance - the CEO of ZenithCorp, known for creating the most advanced AI in the entire world.
