A useful, though narrow, little book
This is a well-written, opinionated guide to the eastern portion of the Pyrenees mountain range dividing France and Spain. It's a good overview if you're thinking about the area, which is poorly covered by most tourism books. It loses a star just because it's rather old, and as quite a small book, it's poor value for money as a general guidebook.
If you're already considering a trip to this area, I do highly recommend it.
