Renegade (Lost Books, Vol. 3)

One of the chosen has gone renegade. Turning his back on all that he once believed, Billos does the forbidden and enters into a Book of History. He lands in a reality as foreign to him as water is to oil. A place called Paradise, Colorado. He has strange new powers given to him courtesy of a mysterious figure known as Marsuvees Black. The chosen four have survived the desert, escaped the Black Forest, battled the Horde, and added a spirited refugee to their number. But nothing has prepared them for the showdown that Billos, the renegade, will lure them into.
