It has been 106 years since the Demonic Dominion conquered Io. 106 years since they enslaved Humanity, banished the Elves into the mountains, and systematically exterminated the Majiski battle-mages. For the Genshwin—the underground network of Majiski survivors, a brotherhood of assassins, spies, mercenaries, and thieves—it is an age of fear, secrecy, and clandestine war against Io's conquerors. But for Jared, a Genshwin of the highest order, there seems to be no end in sight. No hope remaining. No recourse left...but to become one with the Demons. From the author of the critically-acclaimed Dark Fantasy bestseller ATTRITION: THE FIRST ACT OF PENANCE comes the unspoken tale of the assassin who fell from grace, who would betray everything he knew, everyone he loved...and put Racath Thanjel on the path to becoming the Savior of Io.
