"In Avenue of Mysteries, Juan Diego--a fourteen-year-old boy, who was born and grew up in Mexico--has a thirteen-year-old sister. Her name is Lupe, and she thinks she sees what's coming--specifically, her own future and her brother's. Lupe is a mind reader; she doesn't know what everyone is thinking, but she knows what most people are thinking. Regarding what has happened, as opposed to what will, Lupe is usually right about the past; without your telling her, she knows all the worst things that have happened to you. Lupe doesn't know the future as accurately. But consider what a terrible burden it is, if you believe you know the future--especially your own future, or, even worse, the future of someone you love. What might a thirteen-year-old girl be driven to do, if she thought she could change the future?" -- Book flap.
