Each life is the result of an infinity of choices - choices that separate who we are from who we might have been. This is the tale of the many possible lives of Anastasia Valerie Stein which come to touch one another through a twist in the fabric of spacetime: Ann, unhappy wife and mother in a world much like our own; Val, independent teach in a timeline of scarcity; Stacey, a free spirit with two lovers, and Tasha, strangest of all, a professional sorceress in a world where the Third Reich rules England.
