School Library Journal Review: With her distinct style, Balliett returns to Chicago and the detective work of Calder and Petra, sixth graders at the University School. This time they are joined by Tommy, Calder's former best friend who had moved away for a year. In this architectural mystery, destruction threatens Frank Lloyd Wright's Robie House, and the Wright 3, as the protagonists call themselves, piece together the puzzle that will lead to the building's rescue. While friction initially mars the three-sided friendship, Petra, Calder, and Tommy soon appreciate their individual roles in solving the mystery. Egged on by their unconventional teacher, the Wright 3 utilize Calder's geometric brain, Petra's writing and observing skills, and Tommy's uncanny findings to research and investigate the cryptic messages that Robie House seems to send in its own defense. Balliett elegantly wraps factual information on the building into a dreamy, Debussy sort of mystery in which seemingly random connections in everyday life uncover the hidden enigmas of Robie House and Wright himself. Balliett's atmospheric writing encourages readers to make their own journeys of discovery into art and architecture, creating a mystery subgenre that is as unique as it is compelling. While the book is not perfect???the final chapters jerk rather than flow, and the Wright 3's transition from awkward tolerance to a tightly knit cadre is nothing out of the ordinary???the mystery itself and the perfectly realized setting make this an essential purchase.???Caitlin Augusta, The Darien Library, CT Copyright ?
