I so love this series. In my mind it's been the best of the Aftermath series. (Escape is a close second.)
Of course, there's no way this prison could possibly go wrong. ;)
(I am a little disturbed by the whole "You're not human, so you don't get rights" spiel from Firestorm, especially since what got Mike Miller into this mess was the death of Martian Manhunter. But yeah.)
