Has anyone ever read these books?

From The Two Rivers, To the Blight, The Hunt Begins, etc.?

Are they any different from the real books?

I remember hearing that From The Two Rivers has an extra prologue about egwene. Don't know about the rest.

It does, it is titled "ravens" Its very unneccesary, we learn that Ewgene is stubborn, and ravens are watching the boys of the village. The hunt begins, to the blight, and the second part of the great hunt has nothing different if I remember,

To the Blight has an extended Glossary, and all the books come with illustrations.
