I too just finished Ready Player One. Such a great read. I tend to lean on Good Reads lately for recommendations. But picked up Atopia Chronicles (http://amzn.com/B00DUK1RKY) after browsing popular sci-fi on amazon's best-sellers list. It has great similarities to Ready Player One - virtual presences, future VR challenges, etc. but a very different kind of book (split into multiple story lines, not one continuous story). But that said, if you've not read Snow Crash then drop everything and read that next!
