On a hill on the outskirts of Sweet Valley sits a beautiful old Victorian house. It stood empty until a few weeks ago, when a new family moved in...the perfect clients for Elizabeth and Jessica Wakefield's baby-sitting service.... Identical twins Jessica and Elizabeth Wakefield and their friends from Sweet Valley Middle School thought they'd landed their dream job when they started babysitting for the Riccoli kids. But little by little, their dream job is turning into a nightmare. Andrew Riccoli dreams that someone tried to set fire to his room--and wakes up in a cloud of smoke. Then Gretchen Riccoli dreams she's falling--and wakes up at the bottom of the mansion's dark, winding staircase. The babysitters are getting scared...too scared to close their eyes in the Riccoli mansion.
