Elena Adams is a master of disguise. She's a loving wife, a dedicated art teacher, and a mother living a quiet life in Manhattan. Her peace is a meticulously constructed sanctuary, built on the ghosts of a dangerous past she swore she'd left behind. That sanctuary shatters in a terrifying ten seconds when armed men confront her family. The ruthless, lethal efficiency with which Elena neutralizes the threat goes viral, giving the world and her old enemies a glimpse of the truth. Her identity has been compromised, and a chilling message arrives: "Found you. Time to come home, Ashfall." Now, a powerful enemy from her history has tracked her down, and they aren't interested in revenge, they want her back, and they've targeted her children as leverage. The perfect wife and mother must make an impossible choice: surrender to the darkness she escaped, or resurrect the killer she buried to protect the family she loves. In a world where her past is the weapon, how far will she go to secure their future?
