I am looking for a book that explains puberty to a bright nine year old - preferably more about the emotional and physical changes and less about sex and sexual feelings (not because I am prudish, just that I think she is too young to have all that pushed at her just yet). Dd1 is v bright and quite mature but not at all streetwise, but needs to hear from someone/where other than us that what she is going through is "normal", bless.
