A Universe From Nothing. What There is Something From Nothing.
by Lawrence M. Krauss. This was a very good book that explained some complicated cosmology and theories of cosmic beginnings in a very clear and balance way. The author makes some comments at the beginning about controveries on what science says about cosmic beginnings and what some religious folks say about cosmic beginnings. To his credit, Krauss identifies these differences as topics for another forum rather than his book.
The explanations of how the universe expands, and the meaning of Hubble's data and explanation are as clear and concise and any I have read. This is a readable and informative book.
