A solid introductory text with well-written, clear overviews of most topics associated with volcanoes. Chapter 12 was of particular interest to me, as it focuses on Yellowstone. The editing could have been better--there were a couple significant errors (substituting 1969 for 1959 in one place and 13,000 for 1.3 million in another). The photos, illustrations and graphs supplement the text nicely. I'd recommend it if you want an academic but not ponderous overview of the topic.
