Black ops specialist Aubrey Sentro may be one concussion away from death. But when pirates seize the cargo ship she’s on, she must decide whether to risk her life to save her fellow passengers. Sentro’s training takes over, and she’s able to elude her captors, leaving bodies in her wake. But her problems are just getting started. Her memory lapses are getting more frequent, symptoms of serial-concussion syndrome. As she plays a deadly game of cat and mouse with the pirates, she pushes herself to survive by focusing on thoughts of her children. She’s never told them what she really does for a living, and now she might not get the chance. While her memories make her vulnerable, motherhood makes her dangerous.
