In ''Sarah'', Orson Scott Card uses his fertile imagination and uncanny insight into human nature to flesh out a unique woman - one who is beautiful, tough, smart, and resourceful in an era when women get short shrift in life as well as in the historical record. ''Sarah'' takes on a vivid reality as a woman desirable to kings, a devoted wife, and a faithful follower of the God of Abraham, chosen to experience an incomparable miracle. Set in the splendor and excess of Egypt and the starkly beautiful desert landscapes of the Sinai peninsula, ''Sarah'' is an altogether believable and provocative drama.
