If you haven’t read Cline’s best-selling novel, it takes place in the year 2044 when most of the world is in pretty bad shape (except for Columbus, Ohio—one of the signs that this is a fictional story). Literally everyone is plugged into a virtual reality utopia known as the OASIS. When OASIS creator James Donovan Halliday dies, it’s revealed that he left behind a series of puzzles leading to to a hidden Easter Egg. Whoever finds the Egg will win Halliday’s real-life fortune and control of the OASIS, like if Charlie and the Chocolate Factory took place inside The Matrix.
