won't be "strictly a novel", but rather thirteen episodic stories that if read together, tells a story arc. Essentially, it's going to be akin to a thirteen episode season of a TV show, but in written form. Interesting, especially if this idea is successful enough to warrant further seasons. Hey, it worked for Joss Whedon and his Buffy the Vampire Slayer comic series, which acts as a "virtual" eighth and ninth season of the show.
I'm certainly excited and can't wait until it comes out!
