Tristan Jones spins a yarn so captivating that one should be forgiven for shunning all contact with the outside world until the very last word has been savoured. He is a true sailor and adventurer who lets nothing get in the way of his ultimate goal of sailing on the highest and lowest waters on earth. This is a tale which shows where tenacity and not a hint of madness can get you so you'll find it cautionary or inspirational. Jones is physically and mentally as tough as they get, which is lucky, because he needs every ounce of his power and knowledge on this journey. If I have just one criticism it's that he can perhaps seem egocentric at times sometimes referring to the reader's assumed view of him. Part of the pleasure of this tale is marvelling at the mind that conceived such a journey and had strength to carry it through; his comments on what we think can make him seem conceited. Perhaps, however, this is good enough to permit his occasional gasconism. Tristan Jones' tome has a firm place on my "Favourite books" shelf.
