I bought the 1st 3 tpbs last year and ended up losing interest or getting bogged down before I even got to the 3rd tpb. It's a story that requires a little more concentration than many comics that are out there, and for whatever reason I was distracted enough that I didn't give it a good chance and I dismissed it.
However.... recently I have been flying back and forth to NewMexico and decided to grab the Tpbs and read them on the flights. OMG, I am SO hooked on this fabulously written story! And obviously the artwork is superb.
I just bought the next 2 tpbs and am eagerly awaiting them so I can catch up on this series.
If you haven't read this series yet, pick it up. Excellent!!!!
