Milena lost everything when she gave up being a spy and sided with the rebels to take down the Guerra Party - including her freedom. But when she wakes up back in her apartment, covered in scars and the evidence of the Guerras' torture, yet alive and free, she doesn't know what to make of it. Even more surprising is Nate's invitation to rejoin the very people who feel most betrayed by her. They need her, though, to free Alex from the Guerras' underground prison, and she'll need help from the most unlikely sources - the other agents. She's forced to round up her old friends to try to save her new ones, but convincing them seems impossible, and trusting them could be deadly.
