The age divisions are just a general idea. Some children may read a book which is very complex with an advanced vocabulary at a very young age. Some children enjoy more simple books at older ages. Since I am 70 and enjoy these books, I must be one of them. I feel that a positive theme, and uplifting language are essential in children's, and my own, reading.
