From the moment she set eyes on the three Foster kids, Darcy knew being their baby-sitter would be no picnic. But the pay was twice her usual rate, and the job was only for a few hours a day - surely an experienced baby-sitter like her could handle it. But Darcy hadn't counted on the mysterious things that started happening at the Fosters' home after she took the job. She did everything a good baby-sitter was supposed to do: she didn't let the stranger claiming to be from the gas company into the house and she called the police when the burglar alarm went off in the middle of the afternoon. But that wasn't enough to prevent a baby-sitter's worst nightmare from coming true. Now it's up to Darcy to rescue the Foster kids - and herself - from three ruthless kidnappers.
