The Baby-Sitter IV — R.L. Stine

Don't live in the past. That's what they say. So Jenny's trying. Trying to forget all of the horrible baby-sitting experiences that landed her in the hospital last year. But now Jenny's in a new house. In a new neighborhood. And Jenny's new neighbor, Mrs Warsaw, wants her to baby-sit.

Poor Jenny. If only she could "just say no" to sitting.

Because someone is watching Jenny. Waiting for her. someone who hates baby-sitters. someone who wants her ... dead.
