Surprised by Love, Heart of San Francisco Series by Julie Lessman and published by Revell Books.
Shy and unattractive as a child, Megan McClare has always been teased by her classmates. But when she returns home from her senior year in Paris, the wallflower has suddenly blossomed into a beauty. With ambitions to become a lawyer or doctor, Megan accepts an internship at the district attorney's office only to discover that she will be working with Devin Caldwell, a boy who mercilessly mocked her at school--and with whom she was hopelessly enamored. She turns to her dear friend Bram Hughes for support and advice. But Bram's vision is clouded by his sudden unwelcome attraction to a girl he had always thought of as a kid sister. He advises forgiveness, but can he forgive himself for pushing the woman he loves into the arms of another man?
