The Shannara Chronicles

Thousands of years after the fall of Humankind, the Four Lands is threatened by an evil Demon army. The fate of the world rests on the shoulders of an unlikely trio: Amberle, an Elvin Princess who dreams of a life outside of the palace walls; Eretria, a beautiful, wild and wily Human Rover; and Wil, a Half-Elf, Half-Human who knows nothing of the great destiny that runs through his veins.
