Like so many teenage girls, 17-year-old Amy Boxer decides she's had enough of school, home and parents. She makes elaborate arrangements to leave the life she's in and start another. Leaving a note for her mother telling her not to bother looking, because she will never find her, she vanishes.
The two stories are only linked by the fact that the anguished parents of missing Amy are the principals in the search for Sasha. The contrasts between clever, chess-playing Sasha placed in a terrifying situation and the carelessly impulsive Amy who has no thought for the consequences of her actions, are very well-drawn.
