Rory Hawthorn knows her family's magical library contains an endless array of secrets, but even her fellow biblio-witches little expect a corridor that's been missing for over two decades to suddenly materialise again. They don't expect it to put a curse upon Rory's aunt Candace, either. With the library once again at the centre of a potential disaster, can Rory help her family unravel the mysteries of the lost corridor and break the curse, or will she be the next to succumb?
