Harley Quinn has the cosmic opportunity of a lifetime-becoming the “Galactic Angel of Retribution” for the Lords of Chaos and Order! But to prove herself worthy, she must survive six suitably bizarre trials, including teaming up with Batman, getting turned into a giant bug, fighting space aliens, and surviving Gotham City after its transformation into a deadly medieval fantasy RPG. Collects issues #55 and 57-63.

Harley is trapped in S.T.A.R. Labs with no escape! Abandoned and alone, the former Clown Princess of Crime must face down a horde of invading interdimensional aliensÉbut is she locked in there with themÑor are they locked in there with her?

Harley was certain she could have it all: She could be the world's best landlord, protect Coney Island from the scum of the Earth, woo Mason Macabre, work her day job as a psychiatrist, volunteer at the puppy shelter...but that's a whole lot of spinning plates, and eventually they're bound to start breaking! What happens when a psychopath cracks up? Is it possible for Harley to go even more insane?!

There are eight million stories in the naked city. Here's one you might have heard: an out-of-town girl moves to the Big Apple after a bad breakup, looking for a new job, a new love, and a new life. Oh yeah, and she's a criminally insane super-villain who just got jilted by a psychotic clown. Did we not mention that yet? She's Harley Quinn, and she's come to Coney Island looking to settle down and cut loose. But where Harley goes, trouble follows. Someone's put a price on her head so big every bounty hunter in Brooklyn is looking for her. Now this newly minted Noo Yawker has to count on her motley crew of new neighbors—and a few of her good old bad-girl friends—to get the last laugh on whoever's gunning for her.
