This was the conclusion to Boxers and used characters and events from the previous book, so it would be very helpful to read Boxers before reading this book. I was able to get through this book fairly quickly, but I was a little disappointed that this side of the story wasn't as developed as Boxers was developed and felt that the author shortchanged the readers with the second half, but maybe there wasn't as much material to work with as there may have been with Boxers.
But being that its been several months since I read this book, my recollection isn't that great, but as a whole, it is one that I would read, particularly if I am a fan of graphic novels.
