In 1972, Richard Forthrast, the black sheep of an Iowa farming clan, fled to the mountains of British Columbia to avoid the draft. A skilled hunting guide, he eventually amassed a fortune by smuggling marijuana across the border between Canada and Idaho. Parlaying his wealth into an empire, Richard developed a remote resort in which he lives; he also created T'Rain, a multibillion-dollar, massively multiplayer online role-playing game with millions of fans around the world.

But T'Rain's success has also made it a target. Hackers have struck gold, unleashing REAMDE, a virus that encrypts all of a player's electronic files and holds them for ransom. They have also unwittingly triggered a deadly war beyond the boundaries of the game's virtual universe - and Richard is at ground zero.

Racing around the globe from the Pacific Northwest to China to the wilds of northern Idaho, Reamde traverses worlds virtual and real. Filled with unexpected twists and turns in which unforgettable villains and unlikely heroes face off in a battle for survival, it is a brilliant refraction of the twenty-first century, from the global war on terror to social media, computer hackers to mobsters, entrepreneurs to religious fundamentalists.
