As a mother, I am both pleased with and a bit put off by this book. I think it is an absolutely fantastic idea, and I'm sure every parent and every young child can relate to. The parts that put me off and makes me hesitate to recommend it is that the child asks his mother if they can go naked on a hot day, which wasn't so bad, but when Nobody shows up and Foster asks him if he is naked, that creeped me out. One other line that bothered me was when he "had a long pee." I didn't think that was necessary for moving the plot forward. Otherwise, if a parent can handle the disturbing image of a mysterious naked visitor visiting their child in the middle of the night without their knowledge, the book is good.
