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. But 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.

Days after Oasis founder James Halliday's contest, Wade Watts makes a discovery that changes everything. Hidden within Halliday's vault, waiting for his heir to find, lies a technological advancement that will once again change the world and make the Oasis a thousand times more wondrous, and addictive, than even Wade dreamed possible. With it comes a new riddle and a new quest. A last Easter egg from Halliday, hinting at a mysterious prize. And an unexpected, impossibly powerful, and dangerous new rival awaits, one who will kill millions to get what he wants. Wade's life and the future of the Oasis are again at stake, but this time the fate of humanity also hangs in the balance.
