I don't know how, I don't know why, but there are 2 forms of the Paperback Contagious!
One to be released on Aug 20th- from what I can see the original official release
But Amazon has listed a new release version: Jan 8th!!!
I just ordered mine and it should arrive sometime after Jan 15th.
I'm very happy now. Having to wait until March (as MuchAdo has promised to get me a signed copy from Houston- but takes a long time tos ship) I now know I can read this book before Some one on here accidently ruins it for folks.
