It's sort of a graphic novel, so I divided the page count in half.

Once I was reading about certain webcomic styles, and came across the notion of "constrained" comics that force a rigid set of rules on each edition. That led to reading about this book, in which the author/illustrator takes a simple 9-panel comic and comes up with 99 different ways of representing the story, via tricks like point of view, mimicking other comics' styles, or combining art forms.  I was fascinated by the examples on his web page. Fascinated enough to request the book from the library, not to buy it, though.

Apparently, it's based on an earlier work "Exercises in Style" in which another author does the same thing but to a story instead of a comic.
