With a ragged peace in place, demons burn farmlands, violent Reivers roam the wilds and plague has spread beyond the Black Meadows. The country is on its knees. In a society that fears and shuns him, Aranok is the first magically-skilled draoidh to be named King's Envoy. Now, charged with restoring an exiled foreign queen to her throne, he leads a group of strangers across the ravaged country. But at every step, a new mystery complicates their mission.

The Omehi people have been fighting an unwinnable fight for almost 200 years. The lucky ones are born gifted. One in every 2,000 women has the power to call down dragons.

Young, giftless Tau knows all this, but he has a plan of escape. He's going to get himself injured, get out early, and settle down to marriage, children, and land. Only, he doesn't get the chance. Those closest to him are murdered....

After the War of the Gods, the demons were cast out and fell to the world. Mankind was nearly eradicated by the seemingly unstoppable beasts until the gods sent the great hero, Ramrowan, to save them. He united the tribes, gave them magic, and drove the demons into the sea. Ever since, the land has belonged to man, and the oceans have remained an uncrossable hell, leaving the continent of Lok isolated.

The galaxy remembers Hadrian Marlowe as a hero: the man who burned every last alien Cielcin from the sky.

He was not a monster. He was not even a soldier. Fleeing his father and a future as a torturer, Hadrian finds himself stranded on a strange, backwater world.
