This collects #17-20 and the first two Specials. The regular issues have an incredible story of an chemical attack on a protest march. Great stuff from Vaughn and Harris. But then there's the two-part special with the guy who talks to animals. All I can say to that is "Huh Wha?!" Is this all just shoehorned in for the first time or was any of this mentioned in the main book? Not that it matters either way because it just didn't work. So, Ex Machina remains on the library reading list but has yet to put together a single solid trade all the way through.
