Wow. Where other writers get on their soapbox and show the subtlety of a small nuke when writing a story like this, Greg Rucka simply tells a compelling story about people and the choices that they make. Showing the depth of the character, regardless of sexual orientation, will do more good than standing on a platform and spouting platitudes.
Rucka, for me, really nailed this arc with his depiction of Renee's family. It was disappointing and also wonderful to see the reactions of Montoya's co-workers. Some of the badgering that she received for coming out as a lesbian was upsetting, although I'm sure true to many lives. Her partner's reaction, his loyalty, however, was inspiring. Maggie Sawyer made a nice sounding board for Renee.
The addition of two extra chapter, Batman Chronicles #16 and an issue of Detective Comics, set the backdrop for Harvey and Renee's relationship, although I'm not sure how Renee deduced that Harvey was framing her. That part was strange. I like the subtle presence of Batman, without him actually doing much, in this series. Bruce Wayne's lawyer showing up to represent Renee was a nice touch.
Lark's art was very good. In the previous book, I thought that it was very hard to distinguish the characters, but with a smaller cast, Lark was able to nail everyone's look, and his gritty, grounded style remains a perfect fit for the streets of Gotham. But, really, forget the crime drama, forget the super-villain - this was a story about a woman learning that she has to accept who she is, and it was brilliant.
