On the cusp of the great age of disco, and in a part of Brooklyn a million miles away from Manhattan, livesfifteen-year-old Valentine Kessler and her long-suffering mother, Miriam. Valentine -- Jewish, pretty, and a touch flaky -- is an unremarkable teenager except for two things: she is a dead ringer for the Virgin Mary as she appeared to Bernadette at Lourdes, and her very being, through some inexplicable conspiracy of fate, seems to shatter the dreams and hopes of people around her. John Wosileski, Valentine's lonely math teacher who adores her from afar, embraces the martyrdom wrought by his unconditional and unrequited love. Joanne Clarke, the bitter and sad biology teacher who schemes to be John's wife, reviles Valentine to eventual self-destruction.
