Batman Vol. 9: The Tyrant Wing is a good book. Batman is pushed to the edge of his limits here. This is not just because he's working with the Penguin (though the way the Penguin persuaded Batman wasn't entirely convincing to me) but also because he's deep into desperation in trying to figure out Bane's plan. Yet, as he does so, his brutality increases, thereby resulting in much conflict and tension with Commissioner Gordon and the GCPD. The conflict is written well as is Batman's struggles. It culminates in a great twist.
This was followed up with some short stories (Batman Secret Files #1). They talked about the effects that the Scarecrow gas had on one officer, drones being used for criminal activity, Batman teaming up with Detective Chimp (Bobo), Batman dealing with physical and emotional pain, and Batman hunting for Man-Bat while in the snow. There were some good emotional moments in them. I especially liked "True Strength" as it showed the vulnerability of Batman and "One" as it showed the consequences of the weaponry developed by Wayne Enterprises (especially when it falls into the wrong hands). Nonetheless, the stories didn't have the same impact as the main story ("Tyrant Wing") did and some were better than others. Still, they're enjoyable.
Batman Annual #3, the final story in this book, was solid. The main antagonist, "The Drone", was a three dimensional character who posed quite a challenge for Batman. He wasn't what made the story great though. The best part of it was Alfred. Tom Taylor, the author of this short story, beautifully illustrated how devoted Alfred is to Bruce as well as how selfless he is. It's a moving story and the ending was superb.
Overall, "Batman Vol. 9: The Tyrant Wing" is a solid book. The short stories were a mixed bag, but they ended well and the main plot was good. The characterization was great throughout also. I like the art too. Thus, it is a good read.
