My One Hundered Adventures by Polly Horvath

Jane loves her house by the sea, her mother and brothers and sister, the ripe strawberries and oysters that her mother harvests from the wild, and always the sound of the sea. But she also longs for adventures—for something out of the ordinary. Is that why she finds herself aloft, alone in a hot air balloon, dropping Bibles to the people below, and having her fortune told by a mysterious stranger? Life does take some unusual twists for Jane the summer she prays to have one hundred adventures, and things will never be the same.
