«'… a crystal clear guide for a first trip around the black hole block.' Gilbert Taylor, Booklist»

«'Kitty Ferguson marshals her arguments well, taking a bite at a time and giving the reader the opportunity to digest before cramming in the next … Her text is carefully thought out, vivid and accurate … A sensible index and suggestions for further reading round the whole thing off nicely. I am glad I read it.' Roger O'Brien, Journal of the British Astronomical Society»
