E.L. Konigsburg revisits the town of Epiphany to tell the story of Margaret Rose Kane, Connor's older half-sister. It's about the summer when Margaret Rose turned twelve--the same year that Cabbage Patch dolls were popular, that Sally Ride became the first woman to go into space, that El Nino turned the world upside-down. Margaret Rose begins her summer with a miserable experience at camp, from which she's rescued by her beloved, eccentric uncles. Little does she know that her uncles, in turn, need rescuing themselves--from a tyrannical city council determined to tear down her uncles' life work--three spectacularly beautiful towers that her uncles have been building since before Margaret was a baby. A rousing book about intelligence, art, and the fierce preservation of individuality, from EL Konigsburg.
