Tallie Brown has spent a lifetime hiding from the ghosts of someone else's past. Raised by a paranoid woman on the run, Tallie learned from an early age how to disappear. Now she must employ her unique set of skills to track down hundreds who have simply vanished, so when an Amber Alert wakes her in the night, she is the first to respond to the call. But tracking the missing girl comes with unexpected consequences, leading her down a deadly path paved with lies and personal loss that ends in a single devastating truth: General Cai Kaswell, the father she just discovered and the world's best hope for peace, is among the vanished.

As she struggles to find General Kaswell, Tallie is drawn into a conspiracy that links her past to the string of unsolved disappearances. Her search for answers sends her around the globe, but when it nearly takes the lives of her trusted friends and leaves her alone, she is assigned to a charming operative she doesn't fully trust. Forced to watch her own back as she searches for General Kaswell and the others, not only does she discover she is the unwitting catalyst for the disappearance of the missing people but she and her father are also lured into a plot that threatens the Constitution and the balance of world power.
