Publishers WeeklyPike (the Wings series) opens a new series with a plane crash, and soon lays out more themes popular in recent YA—inexplicable survival, loss of memory, an unknown stalker, apocalyptic showdown, and the protagonist's transcendent secret identity. Tavia, the 18-year-old survivor, is in rehab and finishing her senior year online. She has time to look at the world with attentive eyes, and what she sees is often unnerving: glowing triangles on the historic houses of Portsmouth, N.H., or pedestrians who flicker. She tries to attribute these visions to the brain injury she sustained in the crash, but she can't dismiss the stalker with a blond ponytail so easily. Nor do the important people in her life—Elizabeth, an uncannily insightful therapist, and Benson, a sympathetic library intern—encourage her to ignore the growing strangeness.
