Black as Night by Cynthia Rayne

Black Soul

Nox is an ex-Army Ranger sniper who’s only good at one thing. Killing. He was willing to do whatever it took for the greater good. But he grew colder, pushing everything and everyone away. And that’s why Nox keeps women at arm’s length, preferring to play kinky sex games rather than date anyone, and let them meet the real him. Until he meets Maeve. Nox can’t get close enough to her.

Black Heart

Growing up wealthy, Maeve had every advantage, every privilege. She flirted and fooled around with men, but never took them seriously. The only person who mattered to her was Amy. When her little sister disappears, Maeve is beside herself. So, Maeve hired Black Star Security to find Amy, but Nox is a real pain in the @ss. Unlike everyone else, he doesn’t jump to do her bidding. In fact, he gives her orders. And when he’s in charge in the bedroom, it melts her.

But can they deal with each other in the cold light of day? And will they find Amy?
