The December book is out:
L. E. Modesitt, Jr - The Towers Of The Sunset.
This is Book Two in the
Recluce series. Tor explains that they are giving away Book Two instead of Book One because the first book is already on sale for $2.99 at all the major ebook sellers. They also note that
The Towers Of The Sunset, while being the second
Recluce book, is a standalone story.
