NEED MORE.

I'm almost done Ready Player One and I've never been this absorbed in a book before. I just started reading this year and I'm trying to figure out which genre is my favourite. This book surpasses anything I've read so far. I'm not a huge gamer but I love the obscure 80's references, the adventure, the thrill... everything about it. What are some books similar to this (not necessarily gamer -related) I just want something else I can't put down. Thanks :)
