We’ve gotten a few requests over the years along the lines of “You should totally do a book with all the X comics in it!” We always thought it was a neat idea, but never got around to it.
They’re called The Devil’s Shorts. Each book is a collection of related Devil’s Panties comics with some new material thrown in. The first two, by popular demand, are Cats and What Not To Say in the Bedroom.
I think you’ll enjoy them, and maybe someone you know will too: We’ve tested them, they’re stocking approved.
