Wow. This was fantastic! I just finished it and cried for a solid 3 minutes after. Make sure you read the personal story Scott McCloud writes in the afterword (it's the reason I cried). This is a MUST read, especially if you like comics/graphic novels. It's about David who is an artist, a sculptor, who's been having a hard time. He makes a deal with Death and the story goes from there. This is a very thoughtful, well-written and well-drawn book. Seriously, go read it now.
