In a day when girls were barely educated at all, Caroline Herschel's father taught her math and music...until, suddenly, he died. Her mother saw her as little more than a household servant. Caroline might have been doomed to a life of drudgery and dimness if not for her brother, who took her from Germany to England. There they started building telescopes in their free time, gradually making them larger and larger, and discovering new comets—even new planets! When the great astronomers of the day wondered how Caroline and her brother accomplished this and came to see for themselves, they found that the Herschels had made the best telescopes of their time. In this delightfully imaginative retelling of Caroline's career, her fairy godmother is none other than her own bright intelligence, hard work, and passion for science.
