Harley Quinn Volumes 1,2 and 4

 

Here's a brief overall of three of the volumes of this series:

Volume One - Die Laughing - In this series we continue to explore Harley's relationship with Poison Ivy while Harley creates a gang of Harleys to fight crime - for a fee, of course - while also aided by a cast of wacky'n'improbably characters, including a Glenn Danzig lookalike! Plenty of other friends'n'foes as they fight off otherworldly zombies, intercontinental cases, punk rock, and cameos by the Joker and the Penguin.

Volume Two - Joker Loves Harley - Here we get even more details of the relationships with Ivy and the Joker, while Harley is also involved in extreme roller derby (is there any other kind?), hallucinogens, and mainly an imposter Joker, who even almost fooled Harley temporarily - not to mention vampires and Harley saving Santa Claus!

Volume Four - A Call to Arms - (I got these from the library and Volume 3 wasn't there, at least at the time) - This volume highlights the Gang of Harleys and gets into some of their characters a bit more as they fight a mutant Popeye! There are various other fights, still more hallucinogens, the continuing tale of the Joker and Ivy, as well as the Catwoman, and lots'n'lots of other weirdness.

Fun stuff, but also fairly over-the-top is the absurdities, but that's what Harley is all about, apparently!
