Eastern Standard Tribe

Eastern Standard Tribe is a 2004 novel by Cory Doctorow. It is the sequel to Down and Out in the Magic Kingdom and A Place So Foreign and Eight more. Like Doctorow's first two novels, the entire text was released under a Creative Commons license on Doctorow's website, allowing the whole text of the book to be read for free and distributed without his or his publisher's permission.

The protagonist, Art Berry, has been sent to an insane asylum as a result of a complex conspiracy. The novel takes place in a world where online "tribes" form, where all members set their circadian rhythms to the same time zone even though members may be physically located throughout the world.
