Twelve-year-old Miranda, a latchkey kid whose single mother is a law school dropout, narrates this complex novel, a work of science fiction grounded in the nitty-gritty of Manhattan life in the late 1970s. Miranda's story is set in motion by the appearance of cryptic notes that suggest that someone is watching her and that they know things about her life that have not yet happened. She's especially freaked out by one that reads: "I'm coming to save your friend's life, and my own." Over the course of her sixth-grade year, Miranda details three distinct plot threads: her mother's upcoming appearance on The $20,000 Pyramid; the sudden rupture of Miranda's lifelong friendship with neighbor Sal; and the unsettling appearance of a deranged homeless person dubbed "the laughing man." Eventually and improbably, these strands converge to form a thought-provoking whole. Stead (First Light) accomplishes this by making every detail count, including Miranda's name, her hobby of knot tying and her favorite book, Madeleine L'Engle's A Wrinkle in Time. It's easy to imagine readers studying Miranda's story as many times as she's read L'Engle's, and spending hours pondering the provocative questions it raises. Ages 9-14.
