My sci-fi comedy series The Martian Confederacy is currently being serialized on Go Comics. A collaboration between myself and Jane's World creator Paige Braddock, the book follows the adventure of three outlaws living on Mars in the year 3535. The entire first volume has been posted and you can read from the beginning here.
The second storyline, FROM MARS WITH LOVE, recently began on the site and starts here.
I've dusted off my treatment for the third and final storyline, STEAL THIS UNIVERSE. With any luck it will be serialized when the current storyline ends.
