Luna Rosati found acceptance and a family during childhood, but when she became pregnant at seventeen, 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 left—the teenage daughter she's never met. Her mentor, Stryker, promises to reveal her daughter's identity, but first Luna must meet him in the old neighborhood, the last place she wants to be. Then Stryker is captured.

Special Agent Corbin King changed his surname 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 toward a greater mission. 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.
