Query: Wonderful Exposition!! As Gripping as a Good Novel.

Dr. Drury has produced a much needed lay-person's exposition of Earth science - Bravo! To paraphrase his words, this book provides the complete story which is sketched out in several contemporary works dealing with life sciences and origins.On the down-side, the reader is forced to read the authors' (short but frequent) political commentary peppered throughout the work. Marx, Engels, Lenin and other economic/political writers are quoted throughout. In most cases, the quotes are forced and read as though they were inserted in spite of the otherwise wonderful text.
