It is about a little girl who is transported to a strange planet through her father's telescope. It is a comic, sci-fi, fantasy for kids with a strong environmental message that was ahead of its time. It is a really lovely, book. Everyone I have heard of who read it as a child says that it is their favourite or one of their favourite books.

I am reading it to DD1 at the moment a chapter or 2 each night before bed and she is loving it too
