All Tomorrow's Parties

All Tomorrow's Parties is a science fiction novel by the American-Canadian writer William Gibson, published in 1999 and the third and final book of the Bridge trilogy.

The novel is set in a near-future San Francisco Bay Area and uses characters who have appeared in the earlier Bridge books: Berry Rydell, Chevette Washington and Colin Laney, who works with the patterns that large amounts of information make visible and who has concluded that the world is approaching a point at which the arrangements of the present will be replaced by something else. The settlement built on the Bay Bridge is where he expects it to happen, and a public relations magnate named Cody Harwood has his own plans for the same moment. Much of the book is spent with people travelling towards that place, including a man who lives in a Tokyo subway station and a courier carrying something he does not understand.

The Bridge trilogy turned Gibson away from the distant futures of his earlier work and towards a near future assembled from the technology of the present.
