From the back cover:

"A cold, foul wind blows through the city of Dorona. The rats lift their noses from the dirty streets in anticipation, for they know the smell of Death when it comes to town. But this wind is human and it bears a name - the name of Shadar Al-Meryk. Shadar Al-Meryk is a name few know, and fewer still speak aloud. Shadar Al-Meryk, the necromantic wizard. Shadar Al-Meryk, the midnight robber of graves. Shadar Al-Meryk, the worshiper of dark and ancient Gods. He has come to the city of Dorona this storm-tossed evvening for a reason. He is searching for something. Something that is not his, but will soon be."
