Then one day, I peek behind the door. From the farthest corner of the basement, bright blue eyes stare at me. Dark hair, fair skin, tear\-streaked cheeks, and lips sealed with duct tape. I am doomed. This woman is my mate. I know that with rock\-solid conviction, and I don't care how much I'm being paid to keep her here. Monster Security Agency is the most elite bodyguard service in the world. These monster bodyguards are lethal, powerful, and determined to protect their clients at all costs. They shouldn't fall in love with their principals, but if they do? Things are bound to explode.

She stole her way into my cold, serpent heart like a thief in the night. The tiny human hires me to shield her from the vengeance of a powerful organization.

A kraken, a scientist, and a love under pressure…. As a kraken bodyguard, I rarely get human clients. When I do, the only way to protect them is to form a telepathic bond.
