The Ladies of the Lake — Jennifer Allison

If you think a school for girls is simply a place to wear ribbons in your hair and expose your dimpled knees, you've never been to Our Lady of Sorrows.

When her mother suggests she apply for a scholarship to Our Lady of Sorrows, an exclusive Catholic girls' school, thirteen-year-old Gilda Joyce is reluctant to agree. After all, why should she trade in her leopard-print jacket and stiletto heels for a goofy pink uniform? But when Gilda learns that freshman Dolores Lambert drowned on the campus and may be haunting the grounds, Gilda goes undercover to explore the mystery at Our Lady. Using all her psychic and investigative skills, Gilda discovers a secret club and the dark truth behind Dolores's death. Solving this mystery will put Gilda in more danger than she ever imagined -- and will put all of her brashness, bravery, and smarts to the test.
