Set in a near future that could very well be ours, Ready Player One by Ernest Cline is prophetic, entertaining and nostalgic.
Briefly, in the year 2044 all our dreams have come true: there are no more fossil fuels, the hole in the ozone layer is no longer a hotly debated myth and despite all those farting cows, there isn’t enough food to go around. Cities are overcrowded and governance is all but corporate. There is an escape, however: The OASIS, a virtual world that offers limitless freedom and possibility.
The creator of The OASIS, James Halliday, is a known eccentric. When he dies, his last will and testament promises the keys to the kingdom (The OASIS and all his vast fortune) to the first person who unravels a series of clues. It’s a game, and it attracts millions of players.
