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.
