What an interesting book! You are immediately drawn into the story of a 7 year old girl Elsa, and her grandmother who is always doing something unconventional and extremely odd. The story is about the relationship between Elsa and her granny and their imaginary kingdom. They live in a flat which is populated with other odd characters. Elsa (and the reader) will meet them all in the course of the story. Everything comes together at the end.
I would say more, but no spoilers! Just read this really good book.
