The Beast Must Die — Francine Pascal

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 big  family moved in . . . the perfect clients for Elizabeth  and Jessica Wakefield's new baby-sitting service .  . .



When identical twins  Elizabeth and Jessica Wakefield began baby-sitting for the  Riccoli family, they soon learned of the kids' bad  dreams. Overactive imaginations, they thought.  But slowly, the terrifying truth becomes  undeniable. The nightmares are real. Something evil is in  the kids' house and in their dreams. Something  that wants them dead.



Elizabeth  and Jessica try to keep the Riccoli kids from  falling asleep, but how much longer can any of them  stay awake? There's only one thing left to do: The  baby-sitters and the kids must enter the deadly  world of their dreams. And morning is a long time  away.
