Secret agent and teenage computer genius Theo Reese lives in two separate worlds—and they're about to collide.

Theo's high school computer-science club is gearing up for a competition, and Theo agrees to lend his knowledge of cybersecurity to help them win. The covert agency he works for also needs his talents. An encrypted key that allows access to the nation's electrical grid has been stolen. Theo's skills are crucial in its recovery before disaster strikes.

When the file shows up at the competition as one of those to be decoded, Theo must find a way to be both an average high school student and Winger, his secret identity. The file must be secured—all while protecting his teammates from those who will use any means necessary to get the file for themselves.
