This was under the category: A Book from your childhood. (It was written in the 80's)
Here is what Amazon had to say about this book:
Twelve-year-old Molly and her ten-year-old brother, Michael, have never liked their seven-year-old stepsister, Heather. Ever since their parents got married, she's made Molly and Michael's life miserable. Now their parents have moved them all to the country to live in a house that used to be a church, with a cemetery in the backyard. If that's not bad enough, Heather starts talking to a ghost named Helen and warning Molly and Michael that Helen is coming for them. Molly feels certain Heather is in some kind of danger, but every time she tries to help, Heather twists things around to get her into trouble. It seems as if things can't get any worse.
This book was cute. It is a kid's book, so there's that. And it was written in the 80's, so it was funny to read the main character say "got out my walkman and listened to some music before bed". (she also used cassette player - which Arlington had no idea what that was). It kept my attention, even though it was for the 8-10 year old range, and it was a quick read (less than 200 pages).
I recommend this book for the younger group. Sure it was written awhile ago, but besides the mention of the walkman, they would not know that.
Stars: 3 1/2
