Book excerpt: Susan and Sarah have always wondered what's in the locked room, the one that used to be Aunt Mary's, at Great-Great-Aunt Flossie's house. Now, after helping Aunt Flossie locate the missing key, they find out at last. Among the "things to save, things to keep" is a big Bible, and Aunt Flossie lets Susan add her name and Sarah's to the family record in its pages. Full color.
