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.
