Bound By Darkness(Alliance (Davies)‪)‬

Determined to rescue Simone from the vampires who took her, Killean must become one of the things he's spent his life fighting-a Savage. As he sinks further into a world filled with death, Killean struggles against his growing bloodlust as he vows to do whatever it takes to save Simone from becoming a monster like him.
When Simone looks up and sees Killean in the middle of her prison, she believes she's imagining things. Soon, she realizes that the vampire who is supposed to be fighting to stop the Savages, and whose kiss made her feel so alive recently, has succumbed to his darkest urges and become one of the things holding her captive.
It's not until Killean tries to rescue her that Simone realizes things aren't what they seem. Even if Killean can save them from the vampires seeking to turn her into a Savage, can she save him from the darkness devouring his soul before it's too late?
Contains mature themes.
