When X discovers that his long distance relationship with C is about to end, he copies her mind and loads her into a virtual avatar in the Net. But in his haste to preserve his high school sweetheart, X forgets to program the one feature he ends up needing most: how to turn her off.

Now it is up to Natalie and G to rescue their friend from the farthest reaches of the Net. Along the way, they must battle a cipher who cannot be killed, a virus that cannot be stopped, and a global conglomerate that will do anything to seize control of the precious Net.
