Scott Sigler wrote a novel and sold it to AOL/Time Warner who published it in 2001 as an ebook that sold quite well.  So well, in fact, that they intended to release it in paperback in 2002 until in a bout of cost cutting they shut down the division that published books like Scott’s.  It took him a year to recover the rights to the book, only to find it impossible to find another publisher willing to release the book.  Not one to let that get him down Scott has come up with a novel way to bring EarthCore to the masses.  From the EarthCore web site:

EarthCore is the world’s first podcast-only novel: you can’t find it in stores, you can’t download the full audio, and the only way to find out what happens is to subscribe to the podcast. This novel is a cross between episodic modern-action fare like "24" and classic sci-fi movies like Predator and Starship Troopers.
