On Amazon and Nightshade's site it is confirmed that a trade paperback of Reap the East Wind is coming in October! From the wording, it will be followed by a reprint of An Ill Fate Marshaling, and then the final Dread Empire book, once and for all! The blurb reads:
"This volume marks the beginning of the end. Reap the East Wind is the
first step on the road to the long-delayed final chapter of Glen Cook's
legendary dread empire series."
