Infidel was written by Christian author Ted Dekker and was released on December 15, 2007.

These new novels span the fifteen-year period that is gapped in the Circle Trilogy's Black and Red.

Stretched to their limits and celebrated as heroes, the chosen will wish they had never been given that thankless task of finding the seven lost Books of History before the Dark One can.

Once there, the chosen four are all caught by the Horde and Johnis is forced to strand Thomas into the desert to die.

An unknown amount of the original copies of Infidel feature Chosen's map.
