Ready Player One by Ernest Cline
The novel “Ready Player One” by Ernest Cline was published for the first time in 2011.
James Halliday created OASIS (Ontologically Anthropocentric Sensory Immersive Simulation), a virtual world that in the 2040s has become in some ways more important than the physical world because anyone can access it for free and build a parallel life within it. When Halliday dies, he leaves his creature as an inheritance to anyone who can first solve a series of challenges based on easter eggs concerning the 1980s.
Wade Watts is a teenager who lives in the poorest area of Oklahoma City and has idolized James Halliday all his life, so he knows perfectly well all the pop references that could be useful to win the challenge. However, he’s only one of the millions of “gunters”, as the easter egg hunters are called, who want Halliday’s legacy. Among them, there’s also the head of operations of IOI (Innovative Online Industries), a corporation that would like to exploit OASIS for commercial uses and has the means to get rid of competitors even in non-legal ways.
