Finished reading this fairly recently. I was blown away.
A masterfully told story about a guy named Asterios Polyp. Mazzucchelli is one of my favorite comic story tellers. The things he's done in this book have broadened my appreciation for comics as an art form even further. What an amazing story drawn perfectly. Really thought out page layouts and graphics. I don't want to spoil it for anyone.
Check it out if you can, worth every penny.

A great write up by someone here that includes more images:
