Linda and Carol Milne, twelve year old twins, discovered that because of a witch’s curse laid on an ancestor, one of every pair of twins born in the family, was doomed to die before their thirteenth birthday. The curse could only be undone by a strange witch’s necklace made up of thirteen linking pieces. To spare their family the girls kept their discovery a secret and set out to track down the 12 medallions and the chain.
