GrimJack Omnibus Volume 1 [COMICS]

I had never really read any GrimJack until I came across this collection at the library, and I thought it was very good.  The premise is a great set up for a wide variety of stories:  Cynosure is a city that serves as a dimensional nexus, with a wide variety of technology and even physical laws varying from street to street.  This allows the main character, GrimJack (a sort of hard-boiled mixture of private investigator and bounty hunter) to get involved in everything from SF to sword-and-sorcery stories and everything in between.  I could definitely imagine swiping the setting for a fun role-playing campaign.
