Batman/Superman (2013-2016) Vol. 4: Siege

Who is Superman’s Joker? Writer Greg Pak (ACTION COMICS) and artist Ardian Syaf (BATGIRL) add a deadly new name to Superman’s Rogues Gallery-one that will test Superman’s strength and Batman’s mind equally!

It’s the Man of Steel’s worst nightmare: an obsessed villain who knows all of Superman’s secrets and is willing to kill all of his allies in order to destroy his true target.

It falls to Batman to track down this murderous madman-but with no clues left behind and no leads to follow, will this killer outwit the World’s Greatest Detective?

Collects BATMAN/SUPERMAN #16-20, BATMAN/SUPERMAN ANNUAL #1 and BATMAN/SUPERMAN: FUTURES END #1!
