Tuck Jameson vows to stop his brother Clay from joining The Body, a religious cult that uses nanotechnology to turn its members into Christian automatons.

But Clay disappears—and in three days, his nanotechnology conversion will be complete. Desperate to find Clay, Tuck enlists the aid of former high school mentor Adam Shimura, now a black ops agent with potentially mixed motives.

Brother Moody, the cult’s Chief Elder, mobilizes his acolytes against Tuck. Worse, a shocking prophecy ups the ante, making Tuck realize the stakes involve not only him and Clay, but all of America—and perhaps, the world.
