Haley Bombauer, aka Flash Jackson, confronts the summer of her seventeenth year with glorious anticipation. She envisions herself roaming the hillsides and forests on her beloved horse, venturing farther and farther away from her sleepy hometown and her overprotective mother. But when Haley falls through the rotted roof of the barn, she is destined to spend the summer in a thigh-high cast, stuck at home with her mother, enduring visits from her spooky grandmother, and pondering the error of her impulsive ways. The year that follows will, in fact, transform not only her life but also the lives of those around her. Set in Mannville, New York, William Kowalski's signature town, here is the story of one young woman's emergence into a world that, in her words, "was not designed with girls in mind" and her efforts to find a way to fit in without giving up her independence.
