The latest novel by the author of the estimable Prep shares many of its strengths. Twin sisters grow up in St. Louis. They’re a lot alike, and they’re a lot like everyone else, except that they have occasional precognitive dreams. Violet grows up to be a psychic, Daisy suppresses her talent and grows up to be a faculty wife, and then one day Violet predicts an earthquake and winds up on the Today Show. A sensitive portrait of relationships, not only between the twins but also a remarkable picture of Daisy and her sensitive, caring, and non-psychic husband.
