Description[]
"Now I know what really scares you. . ."
Jenny was really excited about moving into a big, old house--that is, until she found out it was haunted. But not just by a ghost, but by the ghost of a witch. A witch who likes to scare people with huge spiders and snakes and dragons!
Jenny knows that she can't possibly live in a haunted house. And she also knows that none of her friends will want to visit her. Who wants to hang out with someone and be scared all the time? Jenny knows she has to come up with a plan and fast, or the ghost witch just might get her wish--to have a little girl to scare. . .forever!
