Title: The theory takes second place behind the people
Review: The book is mostly about the personality and adventures of Hoffman. I was quite disappointed at how light and glossy the treatment of the science backing up the theory was. I'm still looking for a book that covers the theory more than the personalities. I suspect that the publisher realized the problem with this work and that is why the hardcover was called "Snowball Earth : The Story of the Great Global Catastrophe That Spawned Life as We Know It" while the later paperback version is called "Snowball Earth : The Story of a Maverick Scientist and His Theory of the Global Catastrophe That Spawned Life As We Know It". The change is subtitle reflects the primary focus of the book. The people and personalities, not the theory and science.
