An excellent issue, a little bit lame in content.
Scott Snyder is one of the best comic-writers you can find on the shelves. He's got that passion in writing not every one has. After a stunning story as the Court of the Owls, the author leads us onto a different road, following Harper Row's life (#12) and now regressing to Batman's "zero year" (which is also to become it's third main story-line, but this is another subject). If #12 was almost perfect, here we find a few lame or not really credible situations, along with excellent dialogues and incredible art by Greg Capullo (as always the best).
Just remember, the first scene (the building/cake) is worth the price.
