For a few days now, I have been reading Frank Miller's Sin City and enjoying it thoroughly. Particularly the first three books: The Hard Goodbye, A dame to Kill For, and The Big Fat Kill.
The art is so incredible at times, I could frame every page. I have to ration the books so I don't run out of them too soon. And I hate to say it, but the last book has been started last night, and probably won't last past tomorrow :)
