"Beautiful Noelle Tremain has just completed AIR training and successfully navigated her first mission. Life is perfect. Until her best friend is turned into a vampire, destroying her day life, and she’s partnered with Hector Dean, destroying her nightlife. He’s the sexiest, most powerful man she’s ever met, able to atomize his arms and punch through anything – but he’s also emotionally distanced, determined to remain alone. So, to stay on top of their case, she might just have to find a way on top of him.
Oh, the naughty things a girl will do for her job . . . "
