"I'm not calling you Daddy," Rowan informed him.
Darius simply chuckled. "Not now, anyway."
"Not ever."
"We'll see."

Vampire Darius Halsen is looking for a boy. It doesn't matter that he's essentially in the middle of a war, where supernaturals have risen up against humanity and are in the process of claiming power. When he finds the defiant Rowan Conti during his duties assassinating human rebels and witches of certain bloodlines, he instantly knows the witch is exactly who he's been looking for...

Daddy kink. No age play. This is a standalone prequel to the Fate of the Fallen series and related book (excepting any other prequels). Because it's set approximately 10 years before the series, there's no need to have read the other books. Most of the other books in the Fate of the Fallen world, unless indicated otherwise, are set approximately 10 years following the prequels: Fate of the Fallen series, Tamed and Trained Trilogy, Need Trilogy, Spoiled and Anticipation, Asymmetry, and Gifts. Daddy and Day Zero can be read independently and have no spoilers.
