I thought that as some of you are reading on an ebook for the first time something a little science fictiony might be the way to go, so I decided to go with Cory Doctorow's "Eastern Standard Tribe". Here's a description from wikipedia:

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. He works in London as a consultant for the Greenwich 0 tribe (though he and his associate Fede are in fact double-agents for the Eastern Standard Tribe). Despite his talents as a human experience engineer, he delivers subtly flawed proposals to them in order to undermine them and enable his own tribe to get a coveted contract. He meets a girl, Linda, after he hits her with his car at 3am....

Here is the book in kindle format from feedbooks. Cory also has it available in almost every format imaginable from ASCII to a Windows Help File.
