Query: A Ghost Story

I read the book "Wait Till Helen Comes" by Mary Downing Hahn. It was really good in my opinion. It had a lot of descriptive words like morbid, reluctant, and aroma. The book also had very good cliffhangers. One example was when Molly, and Heather fell and she left me hanging for the next chapter. If you like scary books this is a good book for you it has a ghost in it. When I read it my knees would start shaking hoping that nothing would happen to Molly, and Heather. Read the book for yourself and see if your knees shake.
