New from Solaris Books: Revenant Gun by Yoon Ha Lee.
About the book, from the publisher:
Shuos Jedao is awake...Visit Yoon Ha Lee's website.
...and nothing is as he remembers. He's a teenager, a cadet—a nobody—in the body of an old man: a general in command of an elite force. And he's the most feared, and reviled, man in the galaxy.
Jedao carries orders from Hexarch Nirai Kujen to re-conquer the fractured pieces of the hexarchate. But he has no memory of ever being a soldier, let alone a general, and the Kel soldiers under his command hate him for a massacre he can't remember committing.
Kujen's friendliness cant hide the fact that he's a tyrant. And what's worse, Jedao and Kujen are being hunted—by an enemy who knows more about Jedao than he does himself...
--Marshal Zeringue
