Sally Huss has almost consistently turned out, in my experience, works of originality, upbeat attitudes, educational in equal measure with colorful and bright, and with fun rhymes to boot. Thus one merely continues her proud tradition.
One could argue here that this is aimed at white female audiences, and plays heavily into the Disney Princess syndrome, which are negatives, but we cannot have every book flooded with every type of person and every kind of wish for our children. There simply isn't room. One simple theme, well-presented with one simple message is fine, and it's up to parents and guardians to seek and pursue diversity by buying (or checking out of the library) a diversity of books! It's really not rocket science! Please don't always expect all options to be covered in one short children's book!
This little girl begins seeing a princess in reflected surfaces: a cup of tea, a bowl of soup, a filled bathtub, and so on. The princess always wants her to do something. The things she wants her to do are always aimed at helping other people: befriending them, being nice to them and thoughtful of them, and each time she does this, the girl helps and thinks she's seen the last of the princess, but the princess never leaves her. I think perhaps you know why. This was delightful, short and easy read, and I recommend it.
