The first half of the book is essentially the third act of the story from the previous volume, and it's a great conclusion that makes great use of the New52 setting (a version of the DC Universe where all different Earths have been merged together), but the other half is made up of one-and-done stories that are of varying quality. I like the story dedicated to Harper Row (because I like Harper Row), but I think the Pennyworth story was unnecessary, and I have mixed feelings on Snyder's reintroduction of Mr. Freeze. Part of the appeal of the character is that he's the most sympathetic villain in Batman's rogues gallery, and this story discards that in favor justifying Freeze's confinement in Arkham Asylum. It's not a bad story, but it subtracts from the character without adding anything really worthwhile to it.So unless you enjoyed Court of Owls and want to see the ending of the story, I'd recommend you give this book a pass.
