After her brush with death at Ian Crane’s compound, Talia Lyons feels like a prisoner, confined in her childhood home. Plagued with seizures - the result of an unidentified drug injected in her neck by Crane’s men - Talia must put her dream of becoming a Hunter on hold. So when Agency Director McDonough asks Talia to go undercover at the School for the Talented, to find the spy who set the trap for her in Nevada, Talia jumps at the opportunity. 

Soon she learns that her newfound freedom comes with a price - working with Donavon on a daily basis. As if that isn’t awkward enough, her former teammate Erik also shows up at the school. But at least Talia has the unexpected company of her best friend, Penny, not only to assist her in uncovering the spy but also to deal with the complications that the guys create. 

As Talia becomes more entrenched in her assignment, she quickly learns the lengths that the agency and Mac will go to in the name of war. With Crane’s influence spreading, Talia learns that there are few Operatives without ties to the Coalition. Forced to face hard truths and dangerous conclusions, Talia realizes that it is those closest to her who are hiding the biggest secrets. As the task of finding the traitor becomes more problematic, desperation and frustration rule Talia’s world. It becomes clear that Talia can’t do this alone. But who can she trust when everyone around her is lying?
