Deliverance

Brion never meant to start a war. But when they murdered his parents and enslaved his sister and his sweetheart, they left him no choice.
Brion of Wexford is the son of a crippled trapper living a quiet life on the edge of the vast and unruly heathland. But when Salassani raiders destroy his world, he must venture into the heathland to attempt the impossible task of finding the girls, rescuing them, and conveying them safely home across hundreds of miles of enemy territory. Now Brion finds himself pursued by men bent on his destruction, deprived of his protectors, and haunted by the knowledge that his murdered father has hidden a dark secret that could reshape Brion's entire identity. Brion must find a way to stay alive long enough to get the girls safely home.
