Jenny Blake has a theory about life: big decisions often don't amount to much, but little decisions sometimes transform everything. Her theory proves true the summer of 1955, when 14-year-old Jenny makes the decision to pick up a penny imbedded in asphalt, and consequently ends up stopping a robbery, getting a job, and meeting a friend who changes her life forever.

Jenny and Miss Shaw form a friendship that dares both of them to confront secrets in their pasts--secrets that threaten to destroy them. Jenny helps Miss Shaw open up to the community around her, while Miss Shaw teaches Jenny to meet even life's most painful challenges with confidence and faith. This unexpected relationship transforms both characters in ways neither could have anticipated, and the ripple effect that begins in the summer of the penny goes on to bring new life to the people around them, showing how God works in the smallest details. Even in something as small as a penny.
