For many writers and artists, spending time at conventions is a regular part of an annual routine. It’s not surprising, then, that some have opted to use genre and comic book conventions as the setting for stories, including one of Evan Dorkin’s Eltingville Club stories, Nick Mamatas’s novel I Am Providence, and Paul Cornell and Marika Cresta’s Con & On. Now, in the new series True Believers, writers Joshua Viola and Stephen Graham Jones teamed with artist Ben Matsuya for a tale of cosplay and horror set at the Colorado Festival of Horror.
