EVEN BEFORE SHE CAME TO BELTON, MINTY CANE HAD KNOWN THAT SHE WAS A WITCH, OR SOMETHING VERY LIKE IT... Minty is the kind of girl who notices things. Pockets of cold air on a stairway. Cries on the wind. Ghosts. On night-time jaunts from the house where she's staying while her mother recovers from an accident, Minty stumbles upon a moondial which takes her back in time. She finds Tom, a sickly kitchen boy, and Sarah, a girl with a birthmark who is only allowed out at night because her family think she has the mark of the devil... Can Minty save her friends, or will she get stuck in the past...?
