Dahlia’s Kiss by Candace Adams

Before humans ever discovered fire, a bond was forged between the Succubi and Incubi that burned hotter than any flame. When they found their true mate, the need to feed from humans would be forever replaced by the one who completed their soul.
My parents were fated mates – two who should have completed each other beyond eternity. Fate is fickle, though. That eternal bond ended and took my parents with it, victims of their own natures. When an Incubus comes to seal our bond, I wanted no part of it – determined not to fall the way my parents had. When two more appear to claim their right as my mates, it becomes harder to ignore the instinct to be theirs.
Maybe I didn’t have to choose, but just as I start to give in to their desires, someone begins killing the humans who’d sustained me in the past. As the Incubi accuse one another in a play to be my only mate, the end of my eternity draws closer than ever. I do know this for certain, I need to uncover the truth before the next victim is me.
