Aganetha Smart, a former Olympic athlete now lives, at age 104, in a nursing home, alone and forgotten by history. For Aganetha, a competitive and ambitious woman, her life remains present and unfinished in her mind.

When her quiet life is disturbed by the unexpected arrival of two young strangers, Aganetha begins to reflect on her childhood in rural Ontario and her struggles to make an independent life for herself in the city.

Without revealing who they are, or what they may want from her, the visitors take Aganetha on an outing from the nursing home. As ready as ever for adventure, Aganetha's memories are stirred when the pair returns her to the family farm where she was raised. The devastation of WWI and the Spanish flu epidemic, the optimism of the 1920s and the sacrifices of the 1930s play out in Aganetha's mind, as she wrestles with the confusion and displacement of the present.

Part historical page-turner, part contemporary mystery, Girl Runner is an engaging and endearing story about family, ambition, athletics and the dedicated pursuit of one's passions. It is also, ultimately, about a woman who follows the singular, heart-breaking and inspiring course of her life until the very end.
