This fascinating book explores the interplay of geology and biology on earth. From the very formation of the planet to well into the future, the author makes a compelling case, in accessible and descriptive prose, for the interconnectedness of geologic processes and the evolution of life. While the author's background as a mineralogist does make this book especially compelling for people interested in the broad strokes of geology and earth history, there is something in here for any reader willing to pick it up.
