This book was amazing. I first found out about it after watching the famous film by Steven Spielberg. This was really good too and i recommend watching it but the book was longer and more interesting.The story, set in a dystopia in 2045, follows protagonist Wade Watts on his search for an Easter egg in a worldwide virtual reality game, the discovery of which would lead him to inherit the game creator's fortune. He is poor and winning could help him a lot. I give it a 9.3/10 as it had a cool plot and was full of surprises. It would be for ages 9+ i would think. He encounters many mysteries in the game and these are very much like the quests in Harry Potter.
