What are you doing buying comic books from Barnes and Nobles? go to www.diamondcomics.com and search for a comic shop near you. A large one will sell the Hush series in hardcover, with plenty of extras.
Correct me if I am wrong, but the villian you mentioned in the spoiler wasn't hush... Obviously you didn't read the whole book yet? The main villian was actually... err... I guess I can't say, but I never read the last issue, I only got to the issue with jason todd, who ended up not being hush right?
I am reading the gotham knights TURNBACK *I think that is the name* with hush in it right now... That is teh way I found out who hush was... I missed the last few books in the first series *Got to jason todd and that was it* So I didn't know. I've sold DC books before, but until now never collected them... I collect a few titles now, sense I liked both storylines...
