Roth Masters is a protector to the bone. Driven by the losses of his past, he fights side-by-side with Hell Squad to protect the human survivors of the alien invasion. As leader of Squad Nine, he and his team are known for their perfect timing in a firefight. But Roth knows they need more intel on the raptor invaders - something to turn the tide of the battle. And he knows the woman he rescued from an alien facility is hiding secrets he desperately wants to uncover.

Former Coalition Central Intelligence Agent Avery Stillman is still adjusting to her new life. Left with terrible gaps in her memory, she has vague recollections of failed negotiations with the aliens, the invasion, and after that...nothing. Until a hard-bodied soldier pulled her from a tank in an alien lab. Now she's trying desperately to remember, to help fight back, and also battling the crazy attraction to the man who keeps pushing her for things she can't remember.

Soon Roth finds himself torn between his duty and keeping the strong woman he's falling for safe. As the pair head into alien territory to investigate, they are attacked and crash land alone, far from base. They have to work together to survive the aliens, but when Avery finally remembers everything...her secrets could annihilate all they hold dear.
