She saved his life. Now they're in a race to stop a deadly attack.

Former CIA sniper Kadance Tolle possesses a special set of skills and a rare pedigree. She comes from a family of assassins, and by saving Lyndon Vaile's life she risks being found by them. Despite the danger, Kadance feels compelled to help Lyndon discover who is after him and his incendiary research, which indicates that the Ebola virus is man-made and about to be weaponized.

With shadowy figures pursuing them and a mastermind watching their every move, Kadance and Lyndon scramble to stop an impending bioattack at the State of the Union address. When their warnings fall on deaf ears, it becomes increasingly clear that there's no one they can trust--except perhaps each other.
