Ready Player One by Ernest Cline
From the Goodreads website: "In the year 2044, reality is an ugly place. The only time teenage Wade Watts really feels alive is when he's jacked into the virtual utopia known as the OASIS. Wade's devoted his life to studying the puzzles hidden within this world's digital confines, puzzles that are based on their creator's obsession with the pop culture of decades past and that promise massive power and fortune to whoever can unlock them. When Wade stumbles upon the first clue, he finds himself beset by players willing to kill to take this ultimate prize. The race is on, and if Wade's going to survive, he'll have to win—and confront the real world he's always been so desperate to escape."
What do I say about this book? Very light reading, almost to the point of being a young adult book. If you like online gaming, this is a nice beach read.
