Darkmage (The Rhenwars Saga, #1)

The hope of the world rests in the hands of a Darkmage.

The Well of Tears is open and the terror of the night has been unleashed. Now, the last Sentinel left alive with the power to defend his world against the minions of the Netherworld is a man destined to be corrupted into the image of what he hates. In the name of duty, Darien Lauchlin will see oaths forsaken, crowns toppled, friends sacrificed and the land he loves desecrated. For there is a very thin line between duty… and brutal inhumanity.
