In a relatively distant future, a celebrity of marine biology, Ann Kelvin is at the point of death. His assistant asked him to perform a transfer mnèse with a large male sperm whale. She accepts. The transplant was successful and Anne finds himself sailing into the depths of the Atlantic in the skin of this great cetacean. Until she meets a giant squid and marine who throw barrels of toxic and radioactive waste in deep sea. All these people do not want him well ... A short novel or novella (71 pages). This little practiced in our size is called "Novella" in Anglo-Saxon countries. The small publisher Claw ink is one of the few practicing. It is ideal for this poetic and ecological history a hymn sung for the protection of nature. For Ms. Debats, the future is like this and worse. For what is it to live again in the skin of a whale, a killer whale or a dolphin if it is to suffer and yet always the madness of men who respect nothing. A well written text, readable, but unfortunately we do this as tomorrows disillusioned.
