Query: A Great Book

I just finished reading and tremdously enjoying No Apparent Danger. It is a book that has obviously been carefully researched and documented by a very competent geoligist. Victoria Bruce should be congratulated for presenting complicated scientific information and facts to a lay reader in a manner that makes them understandable. At the same time she has woven the information and well-documented facts into a fascinating account of a fateful expedition into the crater of a volcano that is about to explode. Ms. Bruce, when will you write your next book? I can hardly wait.
