As all DK books are good this one does not disappoint for a general astronomy book. It is very good for an interested young teanager and is a good for general interest in the subject.
Too many pages given over to star charts that have little relevance to the amature astronomer, however I enjoyed the book given it's low and cost good quality illustrations and to the point revision if you have read much before, and if not an excellent start!!. Just a good addition to the amature astronemers library.
