Unspoken — Larry McCloskey

Siobhan won't run and her dad won't talk. She loves the piano and Sean loves the marathon. Father and daughter seem to have nothing in common, and how they feel about each other remains unspoken.
But things are not always as they seem. Siobhan and Sean each make a secret sacrifice to the other which speaks volumes, and their quiet, predictable, unspoken lives will never be the same.
