When unexpected side-effects in Gina Xanacovich's nanotech research leads to murder and death threats, her father hires private mercenaries to protect her. But Johan "Alex" Alexander proves to be just as dangerous to her peace of mind as the threats against her life. Worse, his seductive voice and irritatingly calm presence keep Gina on edge, making her want more from him than just being her bodyguard.

Giving into their growing attraction, Gina finds it hard to focus beyond her obsession with the sexy mercenary. She knows if she can't reign in her desire, she won't live long enough to discover those responsible for the murders and threats. Nor will she discover how far things can go with Alex.
