I'm trying to rediscover a book I read long ago. The only things I can remember about this book are:
That this kid is playing the video game he is playing it when he should have been doing his homework.
In the middle of the night he either falls asleep or get sucked into the video game because there's a hypnotic picture thing going on on his computer screen.
His character in the game is a ghoul — the type that feasts on the bodies of dead monsters and people — which gives him extraordinary strength and stuff like that (basically he's a zombie in this game).
He is now in the world of the game, which is a dungeon with companions. The plot of the game is to defeat a necromancer (or something like that) because these people are evil wizards that have summoned him (or something like that) into the game (... I mean in the movie or I mean in the book). He must defeat the evil magician in order to get home.
He has a friend who was supposed to be female but is male ... his name was Chubby? ... he finds his friend outside of the dungeon and discovers they were friends in real-life.
His friend finds out that the clothes are too small for him because they are literally choking the life out of him.
His friend goes on to defeat a Horseman (or a plague caused by the Horseman) that I believe was hurting a Village for a while.
And all the while they are doing this, it is still a video game that he has been sucked into. He finds one guy who is playing it as an avatar, yet he is able to control it through the game people. There are also others who have been sucked into the game, including a girl that has no memory of it being a video game and just thinks of it as real life. She is a Slave (it's similar to World of Warcraft).
