"graphic novel" is a term used by people who write or read comic-books but think this sounds too embarassing or not sophisticated enough
Favourite books?
- A Clockwork Orange (don't care much for the movie, though)
- The Short Timers
- The first three "Hitchiker"-books
- American Psycho
- Fear and Loathing in Las Vegas (in this case, the film is ALSO very good

k: )
- The Dirt
- Michael the Finn by Mika Waltari (not really sure if that's the correct english title, though)
- "Rumo und die Wunder im Dunkeln", "Die 13 1/2 Leben des Käpt'n Blaubär" & "Die Stadt der träumenden Bücher" along with other Stuff by Walter Moers (including some "graphic novels" :bleh:

).
There are indeed quite a few more, just too lazy to list them right now...
EDIT: as for "graphic novels"... don't really care too much for those, really... though I still kinda like the old ORIGINAL "Ninja Turtles"-stuff by Eastman/Laird...
