This is one of the books I bought as a result of s_d. Great mixture of old villains, newly-created ones and the anti-hero Jason Blood/Etrigan. Plus, Slott refreshingly did an Arkham story in which the Joker wasn't running the show. (Hey, I like a well-written Joker tale as much as the next fan but he does tend to, as it were, take over most stories he appears in, so good on Slott for letting some new villains, like the chilling Jane Doe and Humpty Dumpty, shine.)
