Cradle and All (Hardcover, Turtleback School & Library ed.)

Private detective and former nun Anne Fitzgerald is summoned by the Archdiocese of Boston to investigate a strange and unusual case -- the mysterious "virginal pregnancies" of two young girls, one from the privileged estates of Newport, Rhode Island, the other from a poor, remote village in Ireland. What Anne has not been told is the prophecy of the Virgin of Fatima, a secret known only to the Pope -- namely, that one of these girls will give birth to the Messiah; and the other, to the child of Satan. Now caught between the certainty of science and the possibility of a miracle, Anne finds herself at the center of a horrifying battle on which hangs the very fate of humanity.
