I too thought this would be an art book of Amanda Conner's work. Instead, you get a sampling of her comics from 1998 to 2010. Its neat to see how the quality of her work has kept improving over 12 years, but if you are already a fan of hers, you probably won't find anything new here. Otherwise, if you have been away from comic books like me, its a great way to enjoy the work of very talented artist because you get to also see her non-Power Girl comics. The cover and page quality are top notch, so it would be a nice addition to your shelf.
My only problem is with Amazon's description. Besides the script for one of the Wonder Woman comics, I don't think there is single word from the artist herself in the book, which is disappointing as I would have loved to read the stories behind her illustrations or her experiences in the industry. In that regard, this book is definitely NOT on the level of Adam Hughes's wonderful Cover Run. There is an 8-page gallery of covers and sketches at the end, but they squeezed four of them onto each page so it not a great showcase of Conner's talent. Compared to other DC collections (such as Power Girl), you miss out on each story's cover art. I know they are probably done by a different artist, but without them, each of the included stories feel a little incomplete.
Overall, 4-stars because of the quality of the book itself and because it's Amanda Conner. Just don't expect anything new.
