Six years after emerging from a fountain of youth, siblings Bill, Paul, and Annie Carpenter, time travelers from 2022, make their way in 1911. In New York, Bill and wife Cassie finish a year as educators and struggle to start a family, while Annie tries her hand as a society reporter. In Arizona, Paul and Andy Lee, sergeants and brothers-in-law, attempt to keep the Mexican Revolution from spilling across the border. For all, life marches on. Then the soldiers receive new orders, Paul and Annie meet alluring strangers, and the family's fortunes take dramatic turns. In ANNIE'S APPLE, the sweeping sequel to THE FOUNTAIN, five young adults find love, danger, and adventure in the age of factory fires, high society, and the sinking of the Titanic.
