Feast of Souls (The Magister Trilogy, Book 1) Hardcover – January 2, 2007 by C.S. Friedman
 
At the end of her bestselling Coldfire trilogy, C.S. Friedman challenged readers to imagine what a world would be like if sorcery required the ultimate sacrifice-that of life itself. Now, in Feast of Souls, she introduces us to a terrifying world in which the cost of magic is just that...in which the fuel for sorcery is the very fire of the human spirit, and those who hunger for magical power must pay for it with their lives. In this epic tale of nightmarish shadows and desperate hope, the greatest threat of all may not be that of ancient enemies returned, or ancient wars resumed, but of the darkness that lies within the hearts of men.
