Corrupted Crown by Kristen Luciani

My best friend’s sister needs protection and I need a wife.
Kyla Costigan.
I can’t even say her name without my mouth twisting like I’ve just tasted poison.
Because that’s exactly what she is – vicious and stubborn enough to battle the devil himself.
She also happens to be the sexiest, most gorgeous woman I’ve ever laid eyes on…and my best friend’s little sister.
Time has transformed every inch of her into a sultry vixen, but she still has a black heart trapped inside a body I’d die for.
Kyla is also the only woman who can to turn me into a power-hungry and ruthless animal, and right now, that’s exactly who I have to be if I’m going to save my family.
Turns out, we need each other.
So the arrangement has been made.
She-Devil is about to become a Mrs.
My Mrs.
That is, if we don’t kill each other first.
I’m going to need a bigger pitchfork if I have any shot of surviving.
