A mistake from Superman's past has returned, and Metropolis hangs in the balance! As the super-family is betrayed from within and stripped of their powers one by one, Superman sets out on a suicide mission into the Multiverse alongside the unlikeliest of allies: Constantine, the demon Etrigan, and — making his return to Action Comics — Bloodwynd! Plus: During "Beast World" in Metropolis, Dreamer has a run-in with life-changing consequences, and Zod's son begins to suspect New Kandor isn't as peaceful as it seems in the prelude to Kneel Before Zod #1!
