Who She Is - Diane Byington

In the fall of 1967, Faye Smith’s family moves to Florida to work in the orange groves, and she has to start a new school… again. She tries out for the track team, knowing her mother would never approve because of Faye’s epilepsy.
When Faye discovers she has a talent for distance running, she and her friend Francie decide to enter the Boston Marathon, even though women aren’t allowed to compete. Desperate to climb out of the rut of poverty, Faye is determined to take part and win a college scholarship.
After the school bully tries to run her down with his car, a strange memory surfaces—a scene Faye doesn’t recognize. Her parents insist that it’s a symptom of her epilepsy, but Faye thinks they might be lying, especially when it keeps happening. To get her life on the right path, she’ll need to figure out what her parents are hiding and never lose sight of the finish line.
