I read this book before watching the movie, Ready Player One, which is similar but not connected to this book or author. I am so glad I read this book first because the author explains the Virtual Reality world in a way that I understood the technology. It is an interesting read with a lot of technology, a little romance and a good mix of mystery. It was hard to put down, a nice quick read. I wish the ending was expanded more, I wanted to know more but maybe that will be in the next book. Overall, I highly recommend the book. I think the topic is very timely and the story makes you want more.
