In Cosmos, Sagan's triumph as a masterly writer climaxes in this universal masterpiece. The visionary scientist and writer takes us on a powerful and epic journey of discovery, awakening the imagination and stirring the spirit. Even when discussing extremely complex issues and scientific phenomena such as Einstein's theory of relativity, Sagan is able to keep us transfixed on the subject with his unique writing style which keeps readers of all persuasions and levels of experience completely interested and informed. Cosmos is a tour de force, and in my opinion goes beyond the works of people like Stephen Hawking, Marcus Chown and Patrick Moore in terms of its imaginative power and easy impartation of the facts. From beginning to end, we are inspired, enthralled and, most of all, educated. 'Cosmos' is an absolute necessity for anyone studying astronomy - novice, amateur or professional, and is great value for money because it will be read time and time again.
