Mary Fred Anderson, raised in an isolated fundamentalist sect whose primary obsessions seem to involve an imminent Apocalypse and the propagation of the name "Fred," is hardly your average fifteen-year-old. She has never watched TV, been to a supermarket, or even read much of anything beyond the inscrutable dogma laid out by the prophet Fred. But this is all before Mary Fred's whole world tilts irrevocably on its axis: before her brothers, Fred and Freddie, take sick and pass on to the place the Reverend Thigpen calls "the World Beyond"; before Mama and Papa are escorted from the Fredian Outpost in police vans; and Mary Fred herself is uprooted and placed in foster care with the Cullison family. It is here, at Alice Cullison's suburban home outside Washington, D.C., where everything really changes -- for all parties involved.
