Harley Quinn, Vol. 4

I haven't read the last two volumes, but, compared with Vol 1.... well, the art's a lot better, but we're going for something that's more straight-up comedy, which may, or may not, be to your taste. Certainly, there isn't much depth in this, and you have to be in the mood for crazy high-jinks, in what's essentially a spoof of Suicide Squad.

The story sees Harley forced to team up with other semi-reformed supervillains to deal with a menace at the JLA's abandoned moonbase. There's fun with space travel, a hostile alien that keeps making pop culture references and, of course, Harley's general craziness. The more serious side is supposed to be provided by Lucas Fox trying to decide what his legacy as Batwing really means and where he should go next with it... but that part doesn't work all that well, and feels a bit tacked on. But if you don't want any more than a crazy comedy playing with the tropes of Suicide Squad with some cheesy sci-fi elements thrown in, then this delivers what it's aiming to.
