So when I was about 12 or 13 I am 22 now. I read this book maybe 4 times and completely forgot what it was called. I really want to remember what it was because it was the only novel I read and actually enjoyed xd.
It's about a boy who gets a website from someone at his school and he goes on it. When he does, he gets sucked into cyberspace and rapidly ages. He ends up going through cyberspace trying to figure out how to escape. His only hope, if I remember right, is his sister to somehow get him out of the game.
