I discovered a strange thing about the Mania ebook. I was looking at the Upcoming Release at BoB and the epub version will be released on 1st Nov and will cost $4.95(minus small discount).
I can't think of why Kensington would make it available for free for Sony readers a week or two before it goes on sale. Won't that seriously put a dent in the epub sales ?
Maybe they are doing it as a new author promotion
