A supermarket clerk in a small dusty town, 22-year-old Libby is full of dreams but lacks the means to pursue them. When her younger sister Tess becomes pregnant, Libby convinces her not to have an abortion by promising to raise the child herself. When Tess takes off after the baby is born, Libby finds that her new role only increases the challenges she faces. Her already haphazard life becomes ever more fragmented. The baby's father, a Christian rodeo rider, suddenly demands custody, Libby loses her job, her boyfriend abandons her, and her own mother harps on how stupid she was to make that promise to Tess. More than a story of a single mother overcoming obstacles, Sky Bridge, with its painfully honest observations and complexity, leaves readers with a fresh feeling for what it means to inhabit a world in which dreams die, and are sometimes reborn.
