I just finished Ephemera, the book version of vol. 2 of Wonder City Stories - the original serial is on here at wonder_city. Unfortunately, vol. 4 was derailed by writer's block, and then probably by life and/or politics; the first 3 vols. contain everything I'm looking for in comic-book-world fiction.

I also recommend ysabetwordsmith's Love is for Children series and Schrodinger's Heroes.
