Query: A Ghost Story

"Wait Till Helen Comes" is an awesome book. Molly and Michael have a happy life untill their stepdad Dave marries their mom Jean and he brings his daughter Heather the brat. One day in their new house Heather finds a graveyard and a new best friend, they both have something very personal in common. Molly also finds an old house deep in the woods. I would recommend this book to anyone, even people who dont like mysteries, because I didn't like mysteries either but Mary Downing Hahn lured me into reading more of the book and liking mysteries. All I can say is thankyou to Mary Downing Hahn for getting me into reading.
