Twelve years ago, for 12 days straight, the town of Widowsbury suffered a terrible storm, which tore open a gate through which escaped all sorts of foul, rotten things. Strange things and strange people were no longer welcomed in Widowsbury, for one could never be sure of what secrets waited under the surface . . . Adelaide Foss, Maggie Borland, and Beatrice Alfred are known by their classmates at Widowsbury's Madame Gertrude's School for Girls as "scary children." Unfairly targeted because of their peculiarities—Adelaide has an uncanny resemblance to a werewolf, Maggie is abnormally strong, and Beatrice claims to be able to see ghosts—the girls spend a good deal of time isolated in the school's inhospitable library facing detention. But when a number of people mysteriously begin to disappear in Widowsbury, the girls work together, along with Steffen Weller, son of the cook at Rudyard School for Boys, to find out who is behind the abductions. Will they be able to save Widowsbury from a 12-year-old curse?
