The Real World and the App World have finally converged and things aren't going smoothly. Skylar now wonders if she was so intent on stopping the Body Market that she didn't consider the consequences of opening the borders. Many of the people who unplugged have become refugees, struggling to find their place in a Real World they've never known. And those who remained plugged in now face a new threat, a deadly virus that has been set in motion by Skylar's sister, Jude. If the virus spreads, it could mean the total extinction of the App World and everyone in it. Now Skylar and Jude must work together to defeat the mind virus before the App World fades into oblivion.
