A brilliant narrator can bring out hidden depths in a text you thought you knew. Consider Hope Davis' wry rendition of Erica Jong's steamy 1973 novel, Fear of Flying. Davis puts a tart spin on feminist poet Isadora Wing's self-absorbed musings as she travels around Europe making a hash of her marriage while trying to ''give birth'' to herself. Chick lit this is not. Isadora has sex on the brain, but also literature, psychoanalysis, German politics, and what it means to be a woman and a Jew. This production is a marvelous time capsule from that fleeting post-1960s golden age, before AIDS, Prozac, and Caitlin Flanagan.
