Ready Player One by Ernest Cline. So far it’s a popcorn & candy book that’s very entertaining.
About the book – “The year is 2044 and the world is in near-ruins. The Great Recession has taken its toll on the world’s economy, and resources are scarce. The Internet and gaming culture have evolved into a creation known as OASIS (Ontologically Anthropocentric Sensory Immersive Simulation), a massively multiplayer online simulation game created by James Halliday and Ogden Morrow of Gregarious Simulation Systems (GSS), formerly known as Gregarious Games. Halliday, with no heirs or other living family, dies suddenly and leaves a video will to those in OASIS and a book that was dubbed Anorak’s Almanac, a journal written by Halliday himself containing all his thoughts. The video says that whoever can collect three keys (Copper, Jade, and Crystal) that are hidden throughout the universe of OASIS and pass through the matching gates will receive his fortune and controlling stake in GSS. This becomes known as the Hunt and people immediately begin the search for Halliday’s Easter Egg. Those searching for the Egg are referred to as “gunters,” a portmanteau of “egg hunters.” Gunters devote an enormous amount of time to studying 1980s pop culture, the decade Halliday grew up in and was perpetually obsessed with, in the hope it will assist them with locating and solving the puzzles involved with the egg.” from Wikipedia
