Blood Army — Richard S. Tuttle

As the battle lines are drawn, an awesome weapon is forged in the north, an army that will destroy the Alliance before the war has even begun. Join Marcus and his allies as they race to prepare for war. In this penultimate volume of the Amica Saga, they must face Alfor's plots and the fearsome machinations of his nefarious rogue mage infiltrators, but the true danger lies in the coming Blood Army.
