Sweet Miss Honeywell's revenge : a ghost story / Kathryn Reiss

Just before her mother is to remarry and her stepfamily is set to move in, twelve-year-old Zibby gradually realizes that her antique dollhouse is haunted by ghosts, one of whom is out for revenge

Zibby Thorne knows there's something wrong with the shabby dollhouse she bought for her twelfth birthday. She hears strange rustling and ringing noises when there's no one else in the room, and one of the dolls never seems to be in the same place she left it. Most frightening of all, whatever make-believe Zibby plays with the dolls comes true--but in a warped, twisted kind of way. So when her family and friends start having bizarre accidents, Zibby is certain the dollhouse is somehow responsible. Terrified, she tracks down the original owner, and she learns something even more shocking: The dollhouse is haunted--and one of the ghosts who lives in it is a cruel former governess named Miss Honeywell who died eighty years ago. But why is Miss Honeywell still so bent on revenge?
