Luna Rosati found acceptance and comfort with her childhood foster family, but when she became pregnant at 16, she gave the baby up for adoption and left without a word. Now a CIA counterintelligence officer, Luna wants to reconcile her fractured sense of self by finding the only blood family she has --- the teenage daughter she's never met. Special Agent Corbin King changed his last name to escape the shadow of his convicted father serving a life sentence. When he runs into Luna, the object of his failed teenage romance, the two must put their pasts aside and work together to expose a secret that someone is willing to kill for. But when they encounter a kidnapping, missing bodies and murder, the secrets Corbin and Luna are keeping from one another are only the beginning of the threat they face with more than their own lives at stake.
