The games Michael is playing have become all too real. Only weeks ago, sinking into the Sleep was fun. The VirtNet combined the most cutting-edge technology and the most sophisticated gaming for a full mind-body experience. And it was Michael's passion. But now every time Michael sinks, he risks his life. The games are over. The VirtNet has become a world of deadly consequences, and Kaine grows stronger by the day. The Mortality Doctrine - Kaine's master plan - has nearly been realized, and little by little the line separating the virtual from the real is blurring. If Kaine succeeds, it will mean worldwide cyber domination. And it looks like Michael and his friends are the only ones who can put the monster back in the box - if Michael can figure out who his friends really are. From the New York Times bestselling author of the Maze Runner series comes The Game of Lives, the thrilling finale to the Mortality Doctrine series. Perfect for fans of Divergent and The Hunger Games.
