Cory Doctorow's new book 'Someone Comes To Town, Someone Leaves Town' is now available as a free download from his website http://www.craphound.com.
I converted it to Microsoft EReader (.lit) format and he has made it available on his page. However, a few people have complained that the file is corrupt and the font isn't great (it's horrible!) so I have re-done it using the Verdana font and corrected the text from his errata page.
I've emailed it to Cory so hopefully it will appear on his page soon, but in the mean time you can download it from here.
