Ruby is nervous about school and, on the way there, she imagines all kind of dangers lurking which mum explains. This is a very good book, lovely story and great idea. I am not sure it would be helpful to all children though, as it doesn't actually deal with school issues and rather general fear of the idea of school. The story stops at the classroom, when Ruby goes in, so we don't go through a school day with her. Also, of course, more children are driven to school than walk these days. Saying that, as a story my 3 year old daughter loved it. She also liked the little map at the front of the book, which is a good idea and lovely detail.
