When Martin Grace enters the hip Philadelphia coffee shop Cornelia Brown manages, her life changes forever. Charming and debonair, the spitting image of Cary Grant, Martin sweeps Cornelia off her feet, but, as it turns out, Martin Grace is more the harbinger of change than the change itself.
Meanwhile, on the other side of town, eleven-year-old Clare Hobbes must learn to fend for herself after her increasingly unstable mother has a breakdown and disappears. Taking inspiration from famous orphans (Anne Shirley, Sara Crewe, Mary Lennox, and even Harry Potter) Clare musters the courage to seek out her estranged father. When the two of them show up at Cornelia's cafe, Cornelia and Clare form a bond as unlikely as it is deep. Together, they face difficult choices and discover that knowing what you love and why is as real as life gets.
