Kindle Kids Daily Deal for January 6, 2013:
"Today only, save on 13 top-rated titles from the American Girls Collection, a series of short, illustrated, historical fiction books for young readers."
These are designed to go with the American Girls doll collections. They are historical fiction to provide backstory to go along with the dolls (if that is what they are still called). They are all pretty well reviewed (4+ stars each) , written at about the third grade level (age 8)
