“THE BLACK VAULT” part 2! What was meant to be a routine mission to retrieve a “cosmic item” from an undersea fortress has become a nightmare beyond anything the Suicide Squad ever expected. And with half the team down, it’s up to Harley Quinn, Katana, and a demon-possessed graphic designer named June Moore to save the Squad from the most dangerous man in the DC Universe. That’s right...they’re screwed.

And in “Captain Boomerang: Agent of Oz,” Amanda Waller digs deep into the implausibly impressive origins of the Suicide Squad’s most loathsome member to discover the truth the world has been asking for: just who made Boomerang a captain anyway?
