Graphic novels are different than comic books in that they usually have a defined plot line and do not continued indefinitely (like, say, Archie or Batman). (well, that's my definition at least).
My favorites so far are the Sandman(Neil Gaiman) series and Lucifer (who was a side character from Sandman). I've also read Uzumaki, a Japanese pseudo-horror comic, that was amazing both plot-wise and visually.
My mom's favorites of the moment are by Rick Geary. Among other things, he illustrates true historical stories: the kidnapping of the Lindbergh baby, the assassination of Abraham Lincoln.
Does anyone else here read graphic novels?
