Long Island in the 1850s was for Jerusha a place of sudden storms, of queer old houses, and lurking ghosts. Her fear of her surroundings is emphasized by her ship captain father's extended departures and by the talk of spirits with which her Great Uncle's Haitian servants constantly confront her. When Jerusha sees a ghostly form hovering over the moon, she is thrilled with fear and it takes an adventurous summer, a storm, a trip in a balloon, and a warm friendship with three girls her age, to clear the air of ghosts and start Jerusha in the direction of a secure maturity.
