The Blue Ghost

The book is The Blue Ghost Marion Dane Bauer. The book is about a little girl named Liz who goes through a wall and goes to the past. Liz has a grandmother who at the end helps her read a diary they found in a chest. She also met three little boys who Liz heard laughing through the wall. Another older girl who's dad works on a farm and she has to take care of the baby herself and the little boys. The character the blue ghost at the end brings a chest to the house of the older girl and the little boys to help Liz cure the baby.
There are two settings one is Liz's house that her grandmother is selling and the other one is the house of the older girl that the father built and is a log cabin.
The problem is that the baby almost dies of a very rare disease. The way that they solved the problem is the blue ghost brings the chest and has a book of remedies that Liz uses to cure the baby.
My favorite character was the three little boys because they laugh a lot when they play around.
My favorite part of the story was when the three little boys played around and laughed.
I like this book because you never know what is going to happen next.
