Bloody Wishes by Brea Alepoú

They are his enemies, not his desires.
Hyde has a secret. He’s a necromancer: a witch that plays with the dead.
Necromancers have been hunted to near extinction by the vampires. So naturally, Hyde falls for the vampire prince—A man with pretty light green eyes Hyde can’t manage to look away from.
When the prince and his equally alluring companion ask Hyde to help them hunt down some vampires, he becomes embroiled in a scheme that turns his entire world on its head. Especially when Hyde’s human ex-boyfriend shows up needing protection.
Hyde ends up juggling more than he bargained for—including three dangerous and beautiful men.
