"Tubes: A Journey to the Center of the Internet."

Like some heroic cartographer from a Borges story, Andrew Blum plunges into the unseen but real ether of the Internet in a journey both compelling and profound. For the first time, Tubes brings the ‘network of networks’ into stirring, and surprising, relief. You will never open an e-mail in quite the same way again." –Tom Vanderbilt, author of Traffic
