Book excerpt: BOY Novak turns twenty and decides to try for a brand-new life. Flax Hill, Massachusetts, isn't exactly a welcoming town, but it does have the virtue of being the last stop on the bus route she took from New York. Flax Hill is also the hometown of Arturo Whitman - craftsman, widower, and father of Snow. SNOW is mild-mannered, radiant and deeply cherished - exactly the sort of little girl Boy never was, and Boy is utterly beguiled by her. If Snow displays a certain inscrutability at times, that's simply a characteristic she shares with her father, harmless until Boy gives birth to Snow's sister, Bird. When BIRD is born Boy is forced to re-evaluate the image Arturo's family have presented to her, and Boy, Snow and Bird are broken apart.
