Five hardcovers on and I think I'm about done with Ms. Marvel. I still cannot bring myself to empathise with the character. Her siding with the pro-registration Republican-Avengers during that little misunderstanding called the 'Civil War' probably didn't help either. Maybe the problem with volume 5 is that it ties in with Marvel's annual mega event which hasn't been released as a one book collection yet as of this writing. For someone who waits for the trade, I only have a vague idea of what is going on in Ms. Marvel: Secret Invasion.
Tony Stark thinks Ms. Marvel is a Skrull so he sends SHIELD Agent Sum to take her down. Unfortunately, Stark sent Sum to the wrong Ms. Marvel (that is to say the real, human Ms. Marvel). Fisticuffs ensue. The collection ends with her big fight with all those Skrulls in Manhattan and her discovery that the Extra-Super Skrull was a Hydra project which adds more confusion that won't clear up until I read the Secret Invasion trade when it comes out.
The artwork by Melo, Benes and Coelho is the saving grace for this book. Ms. Marvel has always been saved by the artwork. If it wasn't for the cheesecake I would have dropped it two collections ago. It's not a bad comic. It's just a passable comic. Efforts by the art team could make me raise it to being a good comic but only just.
