Math prodigy Hannah Bennett is uneasy about leaving her family and her life on their dairy farm to study for a scholarship in Philadelphia. But such opportunities are rare for a girl in 1934, and going to school in the city is like realizing a dream--at a price.
City life is lonely. The snobby girls are cruel, and Joe, a fellow scholarship student, is teasing and unpredictable. Hannah has her own problems. As compulsive number counter, she imposes rules on herself, sometimes at the expense of her own peace. With the big scholarship test looming and her family wanting her back home, Hannah must find the right equation that determines where she belongs in the world.
