Written by SCOTT LOBDELL Art and cover by KENNETH ROCAFORT and BLOND Red Hood, Arsenal and Starfire enter the Chamber of All to discover what the Untitled wanted - but they'll need to leave their most cherished memories as collateral! And when you're a reincarnated sidekick who lets your madon get the better of you, a former addict turned soldier of fortune, and an intergalactic princess who never quite recovered from a childhood spent as a prisoner of war...? Well, there aren't a lot of cherished memories to choose from! All this as the trio draws ever closer to dealing with a threat that's already killed the ancient caste of assassins who taught Jason Todd everything he knows about the art of killing!
