It appears they were recently (October 2012) made e'available - at least, on Kindle.
That's the good news. The bad news is .. well, the cover art could be a lot better.
|The Coming of the Horseclans|
Remember when it looked like this?
Also good news; unlike some other series that are back that I feel are overpriced, they're holding the Horseclans e'books to $4.99. Still probably cheaper to find the used paperbacks, but really not a bad place to start. Maybe there will be some sales in future.
On the wishlist for now.
