The sequel to Brandon Sanderson's Legion is available for pre-order, and is currently listed as free, over at Audible. If the title sounds at all familiar, the original short story was also free from Audible a couple of years ago. It is due to be released on November 24 and I don't know if it will be free after that (heck I don't even know if it will be free tomorrow) so don't wait long to go
here to get if you're interested.
Enjoy!
