MTV Splash Page has learned that comedian and all-around geek Patton Oswalt has written a brand new comic book based in the world of Joss Whedon‘s wild science fiction western, Firefly.

This will not be the first time a comic book will be set there; back in 2005, Whedon made a 3-part comic series titled Serenity: Those Left Behind. Then, in 2008, he made yet another 3-part comic, this time called Serenity: Better Days.
