The Heart of Hearts, Paperback

Lukas has always known that Nox was different; her crimson eye made sure of that. So, when mysterious wizards kidnap Nox, and Lukas draws from its stone the sword of the legendary Philosopher King, the two collide with a world on the brink of war. Only the holder of the mythical Heart of Hearts, wielder of the Sword Durandal, can save the world of Lythia from utter destruction.
