Ready Player One is one of those books that I'll be recommending to people for a long, long time. If you love geeky media... books, videos, TV shows, music (and especially if it's from the 80s) this book will be a favorite of yours as well.
The characters are engaging, the descriptions of the scenes inside OASIS are vivid, and it's fun (and thrilling) at the same time.
Does the 80s trivia come on a little thick? Yes, but that's kind of the point (and the plot).
