Renegade

In Renegade, the third in the Lost Books series, a YA spin-off of the New York Times bestselling Circle series, one of the chosen will leave his world . . . and enter ours.

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, is luring them into.
