She poured fire into my cold, emotionless heart. Now all I see and feel is her. I’m a cold-blooded killer from the deep, always getting MSA’s most hazardous underwater tasks. Fear and emotion are foreign to me, which makes me efficient but too callous to work with clients. Even though close protection is not my forte, I’m assigned a human principal–a witness testifying against a criminal organization. She is fragile, clingy, and too warm. I hate her instantly, her affectionate nature clashing with mine. But this assignment comes right from the top, and I can’t refuse it. Every minute I spend with her is an annoyance, until we end up trapped in an underwater cave, where her survival hinges on being shockingly close to me. Her warm touch on my body is like a powerful current that tears my shields apart. Her trusting eyes locked with mine destroy my peace of mind. For the first time, I'm flooded with feelings. And they are all about her. I’m addicted, my heart and body throbbing with the onslaught of emotions. The only way to soothe the pain is to get more of her, more touches, more smiles, more affection. I crave her even though I know I’m a monster and a killer, and she deserves better. I’m not selfless enough to let her go. Monster Security Agency is the most elite bodyguard service in the world.
