I wanted to do this since the first day I started Curveball because comic books are awesome. I just couldn't figure out how to make it work price wise. But in January I finally figured out how to make trade paperbacks (er... "prose comic books") of Curveball available on CreateSpace and Amazon.
Short story: I wanted them price-competitive with physical comic books, and as single issues they weren't. But as Double issues--that is, Curveball 1&2, 3&4, 5&6, etc., they were price competitive with the cost of buying two comic books. CreateSpace blocks off their costs in page ranges, and the page count of two issues falls into the same range as the page count for one.
So I'm pleased with that. I really don't expect too many people to be interested in them--this is more of a "ha! I did it! Muahahahahahahaha!" kind of moment for me--but I actually had one purchase so far (before I was even ready to announce them. It was weird. Someone stumbled across Issues One and Two on Amazon and decided "eh, what the hell."
Anyway, my announcement is here:
