This is a revolutionary book, and one expected to make history. Firstly because of its plot, which shows with an enthralling storyline the danger involved for future generations of extracting oil from ten thousand metres under the sea. The drilling techniques in use are still not sufficiently developed to do so, as demonstrated by the recent fire on the Deepwater Horizon rig in the Gulf of Mexico, which caused the greatest environmental catastrophe in living memory. And secondly because, after 500 years of publishing, the author has realized that, just as one of the novel's characters points out, books can be printed in a much more simple, convenient, practical and less costly way, saving a third of the paper and weight without reducing the font size.
