I am reading this to my 5 year old son as a bedtime story, though it would also be suitable for an older child to get reading practise. There are sufficient black and white sketches to keep him interested, nice short chapters to enable me to break it up into bedtime story sized chunks, and the theme is familiar to most children; yearning for something you can't have, in this case Janie wants a great dane dog. Unusually for a child's story, we are privy to parents' discussions about their child, and whether they should let her have what she wants. Seeing things from the parents point of view is an interesting angle absent from most children's stories.
The story is holding my son's interest, and we are both enjoying the book.
