Watch out for those eBooks. The "authors" rip off people's entire websites and sell them as eBooks.
I know, as I have been a victim of this. There is a Christmas cookie eBook that is a carbon copy of my site, right down to the categories and every last recipe. I've also found other examples of this...people's chili recipe sites, stuff like that. They just steal the entire content, stock and barrel, and then make a profit out of it.
