Over on his Livejournal, Nick Mamatas has announced a sale of his novel Move Underground. $5 covers the book, shipping, and even a signature somewhere in the book. I'm sure copies are limited, but what a deal!
The complete text of Move Underground is available online at the book's website (linked above), but there is just something about holding the book in your hand, but check out a chapter or two and if it's good, why not order a book for $5?
I've only read his short story "Who Put the Bomp?", but I have heard nothing but good things about Mamatas' novel length fiction. For $5, it's worth a try. I ordered one.
