Charles (Darkness, #8) by K.F. Breene
Charles is a guy that likes to play the field. He’s highly sought after in the Mansion, both for his prowess, and his position. He’s content to stay the playboy for life, too, steeped in the culture in which he was raised.
That is, until he finds himself on a mission with Ann, trying to figure out why shifters are mysteriously going missing. Suddenly things that were so clear cut, get muddled.
When Ann succumbs to the danger that is plaguing her kind, all bets are off.
