Pros: Well written, comprehensive
Cons: A bit technical in spots, but thorough
If you have any plans to poke around in the backcountry, you should read a book or two about avalanches. This one is a great place to start. A bit more in-depth than some others I've read, but written in a very enjoyable style. If you only plan to buy one book for your reference library, this is the one I'd recommend.
