Batman: Hush

I don't like superheroes, but I love a good story and this book tells a great story full of twists and turns, even if I wasn't the biggest fan of the ending. I really appreciated how fragile and human Batman was through this book, going so far as suffering a life-threatening injury (even if we all knew he'd make it out with only scars). There were also a lot of gray areas with very little white or black, his relationships with his sidekicks, allies, and nemeses being the most obvious.

I don't think this book will strongly change my opinion on superheroes—I'm ambivalent to most superheroes and despise any that don't have a set of rules, limitations, or weaknesses governing them—but I'd be willing to read a few more if someone suggested them to me.
