The end of centuries of war is looming. Ilyas of Vine, War Leader of the armies of the Mad Queen Maevian Oriset, is sent off once again to hunt the deadliest foe he has ever faced: Willow of Herb. Tired of the fighting, but with too much on the line, Ilyas knows that this will be their last fight. This time, failure is not an option. This time, he will kill that damn monster, or die trying. Willow of Herb has fought against Vine all of his life. Ever since the day the Mad Queen’s forces killed his parents, he has revealed in the bloodshed of war. As the only one with a hope of matching Maevian’s power, it is up to him to find a way to put an end to her reign of terror. Only one thing stands in his way: Ilyas. In a war where neither side is truly good or evil, and shades of grey run rampant, who will be triumphant when these two forces meet again for the final time?

Enter the Nine Lands of the Mountain Fell. Skye has only ever known pain and solitude since waking up with neither memories or magic. Hunted for being a Ruler in a time when they are scarce, she has survived in the wilds near the Rim, always on the run from the rest of her kind. Only starvation could draw her close to a village, but when a chance encounter and a bit of bad luck launch her into the arms of a man whose soul is bonded to hers, hiding who she is may no longer be possible. Ilyas is a hunted man. Wanted for killing the last High Queen of Vine, he is plagued by his past of wholesale slaughter. He never wanted another Queen, and certainly not a half-feral, distrustful girl who gave up on the Fae a long time ago. Unfortunately, Soulbonds are not so easily walked away from, no matter how hard they both may want to, especially when trapped together in a cave with a pack of Feral Fae right outside. With long-held enmities breaking out between the besieged villagers and all their lives on the line, Ilyas and Skye must learn to work together and trust each other if they want to survive.

Asherah of Vine died five times in bloody service to her Queen, but now her Queen is dead. The cycle of reincarnation has ended, and Ash is ready to set her trusty bow aside and live out the rest of her days in peace. All she wants is to live a quiet existence on the Rim, but her past, it seems, is intent on catching up with her. She's tried to outrun him, but he's not a man to be trifled with. Willow of Herb has been hunting the butcher Asherah for over two hundred years. She slaughtered his parents and his people, and he intends to bring her to justice. It is because of her that he was turned into a weapon of war, and it is her face that haunts his darkest nightmares. When he finally catches her scent nothing can stop him, but what happens when he captures his greatest enemy and finds out that not everything is what it seems? As they travel through the icy Lands of Nadir chased by a rival band of bounty hunters, Willow and Asherah must face their pasts and learn to work together if they wish to survive. Trust between enemies isn't easy to build, but as they fight Feral Fae, face down snowstorms, and run from Retribution, Will and Ash find that maybe they're stronger as allies than as enemies.
