A great book for reading with your child or to leave them with. I read this cover to cover and feel it describes things very well at a pre teenage understanding. It covers a great deal in a sensitive way, from sex to relationships to dieases, but also covers family set ups and different parenting, i.e gay or adoption. A very extensive book that could be re read and refered to thoughout early teens. I would suggest over 10's but obviously the book needs to be shown to a child when the parent feels it is appropriate.
