The old world of Eryndor is dead. The chessboard has been shattered into ash.
When Prince myr claims the obsidian throne after unearthing a massive northern conspiracy, he doesn't just rewrite the empire's laws-he locks its most dangerous, deadly shadow permanently to his side. Sorren Valek, a brilliant and reckless wildfire assassin, thought his contract with the crown ended when the rebel lords fell. He didn't expect a life sentence bound to an iron-willed sovereign who refuses to let him slip back into the dark.
Meanwhile, in the suffocating shadows of the royal alcoves, a second conquest has already been won. The brilliant chess-master Prince Rael finds his strategic armor completely stripped away by the one man who refuses to see him as a political pawn. Idrien Valel, his quiet and ferociously territorial imperial guard, has already claimed the royal bloodline with his blade-and he has absolutely no intention of letting the high court barter away his prize.
Two powerful pairs. One unbreakable alignment.
