For anyone starting out, this is an excellent general introduction to the whole of astrology. All things considered it is also probably the best. Over 15 years ago, a very similar volume by the Parkers was one of the books from which I learnt the basics of astrology. Their style is accessible, imaginative, and not too heavy. Their latest offering in late 2003 is first class.
Whether you are interested in basic Sun sign characteristics, basic chart interpretation, prediction techniques, relationship or re-location astrology, its all here. The book is divided into five sections, which includes detailed tables for drawing up charts. Beginners should not be put off by the long section on the complexities of chart calculation, even though this is useful information. It is of course very easy to get a copy of your natal chart done by computer, and start from there.
The often beautiful illustrations and pictures add considerably to the quality information in Parkers Astrology. It certainly makes the process of learning astrology easier on the eye! I recommend this book for the beginner, perhaps together with one of the more "serious" introductions, such as The Classic Guide To Astrology by Ron Davison or "Chart Interpretation Handbook" by Stephen Arroyo.
