In June 2010, Cline sold his first novel, "Ready Player One", a book that takes place in a dystopian vision of the 2040s. The book was sold in a bidding war to the Crown Publishing Group (a division of Random House). The film rights to the novel were sold the following day, to Warner Bros., with Cline co-writing the screenplay. Ten months later, with the hardcover release coinciding with the paperback release, Cline revealed on his blog that both the paperback and hardcover editions of "Ready Player One" contain an elaborately hidden Easter egg. This clue formed the first part of a series of staged video gaming tests, similar to the plot of the novel. Cline also revealed that the competition's grand prize would be a 1981 DeLorean. The prize was awarded in 2012. The paperback is currently in its 17th printing.
