The Blood King - Chronicles of the Necromancer, #2

Exiled prince. Mage heir. Necromancer king. Prince Martris Drayke of Margolan escaped the bloody coup that murdered his family and put his half-brother, Jared, on the throne. He fled with three close friends, found allies along the way, and gained the backing of loyal deserters, the undead vayash moru, and the vengeful ghosts of Jared's many victims. In just one year under the usurper's thumb, Morgolan has gone from prosperity to chaos and starvation.
Jared's troops hunt down any who oppose him, filling the gibbets and scaffolds and carrying out a reign of terror. Tris has risked destruction to gain control of his spirit magic, and harness his power. But when he and his allies return to Margolan, Tris must confront Foor Arontala, Jared's blood mage, and stop him from freeing the soul of the Obsidian King from its crystal prison. If Tris fails, Arontala will set the Obsidian King free and take on his power, becoming unstoppable and destroying the last chance to free Margolan from Jared's rule. Can Tris stand against the blood magic of the Obsidian King to take back the throne and save his kingdom-or will his half-mastered magic bring about an even greater destruction? The Blood King is an action-packed epic fantasy adventure filled with magic, occult lore, honorable ghosts, loyal friends, found family, bloody battles, immortal creatures, secrets, treachery, forbidden love-and a necromancer hero! Book Two in the Chronicles of the Necromancer
