Depends on the book, I was never able to get into Sandman despite all the hype about it but I really dug his Mr. Punch book, or anything he does with Dave McKean for that matter.

I've only read his comics, not really into reading the 'books' of comic guys usually, for the same reason I usually steer clear of rockers writing novels too. Exceptions made for autobiography of course, at least when it's Dylan and Keith, or Grant Morrison's book about comics which is pretty damn good.

Right now I'm reading The System of Dante's Hell by Leroi Jones (aka. Amiri Baraka). It's like a black power W.S. Burroughs.
