Axel Martinez lived and breathed life as a Marine until his entire squad was massacred. A chance offer from a multi-billionaire provided him exactly the escape from his past he wanted. Beatrice Li has been a gun-for-hire since she was old enough to pick up a knife. One strange meeting on a rooftop changed her life forever and now she saves the world, one assassination at a time. But when Axel’s life is threatened by a ghost from Bea’s past, Bea’s going to have to use all her strength to keep up her guard—both from those that want to kill her sexy and seductive mechanic—and also from him chipping away at the carefully crafted walls around her heart. His smart mouth and cocky flirtations keep her on her toes, but she’ll give as good as she gets.
