This completion of the Court of Owls narrative from volume 1 was nicely done. This also turned Mr. Freeze into a compelling antagonist, which was something I struggled with ever since the terrible movie depiction of him. I was pleasantly reminded of Alan Moore's "This Mortal Clay" which took and minor and uncompelling bad guy and gave him significant depth and pathos. 
 I also love the unreliability of all the information about the Court and its players and game pieces. We only know what people think and what that have been told, and this whole organization runs on deception and obfuscation.
