Query: Great Book!

This was a fun book. I was afraid it was going to be stuffy and all intellectual, but it keep my interest and had some genuinely amusing moments. I liked the old professor and Miguel, and how their highly unusual relationship helped both of them become better human beings. Several nice surprises throughout, with a great ending. I would say recommended for everyone from teens on up. (Some mild adult situations, language.)
