Heading into his final year at the secret spy school known as the Orphanage, Bennet is hoping to get through to graduation with no hiccups. With the help of his classmate, Darcy, Bennet has moved on from the death of his brother, Collin, last fall. He's successfully started training as a field agent, and he's managed to earn the respect of the agents at the Orphanage with his successful assignment against an oil tyrant last June. He’s confident nothing can stop him from having a terrific final year. But events soon prove him wrong. The Orphanage is frantically on the hunt for the mysterious person known as the Shepherd, who they are convinced is set on wreaking havoc in the world. Bennet and Darcy have been kicked off the assignment and told to focus on their training. But during a routine assignment to Google headquarters, Bennet encounters the last person he expected to see—and barely survives. In the aftermath, Bennet feels like someone is shadowing him every time he leaves the Orphanage. No one believes him except Oliver, the new kid from the organization’s British location. He teams up with Bennet to try to find and stop this unknown shadow. On a class assignment, Bennet and Oliver risk everything to catch Bennet’s shadow and come face to face with a ghost from Bennet's past who forces him to make some difficult decisions. Who is his family? Whom can he trust? Will he become a traitor? Or . . . is a traitor already among them?

Recruited as babies by a mysterious organization known as the Orphanage, sixteen-year-old twin brothers Bennet and Collin mean the world to each other, even though they’re complete opposites. Collin is training to be a field agent while Bennet is an earpiece, in constant communication with his brother, monitoring his activities and providing computer support from a safe distance. When a mission goes horribly wrong, Bennet is left bereft, missing his other half. Already introverted, he retreats into himself. In his final statement, Collin urged him to leave the Orphanage, but it’s the only home he’s ever known. Instead, he makes a drastic decision: he’ll fill the Collin-sized hole in his heart by rejecting his computer-focused career path, trying instead to match Collin’s physical prowess so he can become a field agent like him. Training with Collin’s old girlfriend, Darcy, a skilled assassin, Bennet tries to prove he can be just as skillful with his fists and a gun as at the keyboard, in the face of skepticism from the Orphanage and all of his classmates. As he struggles to succeed, Bennet must question how much he has hurt those around him and how much more important it is to be himself than just a copy of his brother. When his class is given its final assignment, both his new skills as a field agent and his old skills as an earpiece are put to the ultimate test. Failure could prove fatal, not only to himself but to his fellow agents-in-training—the only family he has left. And as if that weren’t enough, the fate of the entire world hangs in the balance . . .
