King - Son of No Man Series, #5

There will be no peace, not even for the people of Espar. The people have suffered long enough under the reign of squabbling princes. Prince Tohmas of Galanth has the perfect solution: supersede the Princes with a King. With the blessing of his Goddess Inac and the strength of the enchanted sword SoulBurner, he will be that King. While half of Espar pledges allegiance, the other half declares war.
Tohmas' eyes turn to his greatest opposition, the Princedom of Trulin, where Prince Kelland is readying his majestic warhorses for battle. Victory in Trulin will only come with persistence and faith, but Inac's favor is becoming fickle. Without Inac, SoulBurner is nothing, and Tohmas' claim to Espar cannot be upheld. As magic powers collide and dragons take to the skies, Tohmas faces a threat his training and years of experience in war are useless against: Prince Kelland's daughter Arnika Trulin.
