The Prince of Hydor - War of the Magi, #4

To become king, Auron must defeat his greatest enemy. As a descendant of the legendary King Eric Garland, savior of Hydor, Auron stands with his father on the precipice of the Garland Kingdom's greatest and final victory over the Magi Rebellion. Once a great ally of humanity, the magi have fallen into darkness and madness. With the glory of their goddess guiding them to victory, they will finally achieve everlasting peace.
At least, that's what his father says. But Auron knows the truth. There is no goddess. The magi do not fall so easily. He is capable of far more than his father or his advisors say. Most importantly, those who oppose him and the kingdom the most lie not on the battlefield. They reside within his own castle walls--maybe even within his own soul.
