Query: Shocking

I read this novel years after its original publication date and I must say that even with the horror novels of today, this book is still a page turner.Reagan, the daughter of a movie star Chris, suddenly begins acting strangely. As the book progresses, every scientific diagnosis and drug available has been tried. Reagan is diagnosed with some for of severe hysteria. With nothing else works to change Reagan increasing distasteful (to say the least) behavior -- and people start dying, Chris turns to a minister to perform an exorcism.You also learn that Reagan has been playing with a Ouija board and speaking with a spirit called Captain Howdy (ever see Strangeland with Dee Snider -- now I know where he got that screen name).All in all it's a great book. If it doesn't terrify you, you'll at least be shocked because Reagan does ALOT of shocking things.
