Yes, I am a dedicated reader of B.M. I find it stunning to learn his ways and views, his practical seamanship and openness. This last work of Bernard's gives a deep moving account of his early life and gives partly new views on aspects that where already issues of his earlier books. Some reader might find too much of mysticism. Granted! However, this world needs such kinds of thoughts and resulting actions as B.M. is telling and was realizing. Don't you think this world would be better if there were more Bernards (and less Ackermanns)?! I say a wholehearted "Yes, I do!".
Whatever, if you're a sailor you could profit very much of Bernard's hints of seamanship. If it has never crossed your mind to set a foot on board of a sailing yacht, maybe you'd get motivated to do so (although that motivation might come even more from the wonderful Seraffyn-adventure-books by Lin and Larry Pardey) - or you simply let yourself immerse into the enticing life of a marvellous character.
Hats off to the the excellent work of the translator (I cannot compare with the French original; nevertheless I very much enjoy the English version)!
To my opinion, if you want to get the most out of "Tamata and the Alliance", you should first read the preceding publications of B.M.
