The Museum of Mary Child by Cassandra Golds

Heloise lives with her mean and demanding godmother.  She lives next to a museum she has never entered. Although she really wishes for one, her godmother does not allow her to make friend's or have a doll. One day she finds a doll and  plays with it in secret. When her godmother finds out, all the secrets surrounding Heloise's past are revealed. I recommend this to fourth and fifth graders, but it doesn't matter. I like this book because it is slightly creepy, but very entertaining. If dolls freak you out, don't read this.
