The Fifth Miracle by Paul Davies, a theoretical physicist who works primarily on the topic of quantum gravity, is a very readable book on the origin of life. Although there is little that is new in the text, the author has put the information into perspective for the reader, discussing a number of aspects and points of view. Probably one of the most salient points he makes is that if , as some would have us believe, life is ubiquitous to the universe to the extent that water equals life, then the basic scientific world view may have to be overhauled. He writes:

In claiming that water means life, NASA scientists are not merely being upbeat about their project. They are making--tacitly--a huge [italics] and profound assumption about the nature of nature. They are saying, in effect, that the laws of the universe are cunningly contrived to coax life into being against the raw odds; that the mathematical principles of physics, in their elegant simplicity, somehow know in advance about life and its vast complexity. If life follows from soup with causal dependability, the laws of nature encode a hidden subtext, a cosmic imperative, which tells them: 'Make life!' And, through life, its by-products: mind, knowledge, understanding.

It means the laws of the universe have engineered their own comprehension. This is a breathtaking vision of nature, magnificent and uplifting in its majestic sweep. I hope it is correct. It would be wonderful if it were correct. But if it is, it represents a shift in the scientific world-view as profound as that initiated by Copernicus and Darwin put together. It should not be glossed over with glib statements that water plus organics equals life, obviously, for it is far from obvious (p. 246).

This book and Rare Earth by Peter Douglas Ward and Donald Brownlee pretty much cover the life in the universe topic for anyone interested in the topic, and both are engagingly written and understandable.
