Laria's Shadows, Book 2 of the Laria Saga

Peace claims the Eternal War. The races, prevented from conflict by the Treaty of Glass, withhold militant relations, but that doesn't stop King Gorlath from mysteriously mobilizing a great host of knights. Anstin Lorice, a young man living in the north, has been accepted as one of Gorlath's new recruits and has impressed the court so highly that he is granted a bride and a place in the succession of the crown under the Prince. His friend Doream, a farmer not as skilled with a blade as Anstin, yearns for a simple life free of Oilic. Oilic has plagued Laria for nearly two decades, and still there is no cure for the dark legacy Foresythe left. After tragedy strikes, Anstin and Doream are thrust unwillingly into the chaos that lurks in the shadows, and they must forsake their old lives to find an escape. Greedy men build Machines against royal decrees, nobles struggle for power, Sion priests deceive their patrons, and secrets and lies become close companions as the frozen war threatens to ignite once more.
