Warbringer (Descendants of the Fall, #1)

Centuries ago, the world fell.
From the ashes rose a terrible new species—the Tangata.
Now they wage war against the kingdoms of man.
And humanity is losing.

Recruited straight from his academy, twenty-year-old Lukys hopes the frontier will make a soldier out of him. But Tangata are massing in the south, and the allied armies are desperate. They will do anything to halt the enemy advance—including sending untrained men and women into battle. Determined to survive, Lukys seeks aid from the only man who seems to care: Romaine, the last warrior of an extinct kingdom.

Meanwhile, the Queen’s Archivist leads an expedition deep beneath the earth. She seeks to uncover the secrets of the Gods. Their magic has been lost to the ages, yet artefacts remain, objects of power that could turn the tide of the war. But salvation is not the only thing waiting beneath the surface. Something else slumbers in the darkness. Something old. Something evil.
