The heroine, Noelle Blanche is a cryptologist. She refuses to accept a grant from the military when they asks for her help in an operation, although it will cause her her job for she wouldn't want blood on her hands should her specialized field be used for violence. But things don't go well as she expects when she finds her house is raided and she has no choice but to seek for safety.

David Wolfe is a former Delta Force operative and he thinks he has finally lay the ugly terrors behind him after the Swarm, a terrorist organization had murdered his wife. But when his former superior seeks for his assistance to work on a mission, he isn't sure if he is able to do it again but when he hears the Swarm members are back, he accepts the mission for he wants to wipe them out this time round.

And the action begins when David and Noelle go on the run until they found a safe place where she can work on breaking the code. It is at this time when their feelings for each other begins to grow but David thinks it is too dangerous for Noelle to be with him and that he doesn't want her to follow in his ex-wife's path. But Noelle has her own thoughts and she has no fear nor regrets being with David.

I enjoyed reading the story and how it flows smoothly, as well as the characters. I am also awed by Noelle's intelligence, as well as her bravery. I will be checking out Shannon K. Butcher's upcoming releases.
