That book is fascinating: the premonition the author had of the coming world war; the description of sailing in that very difficult region and sea. Each detail is true and for people who love the sea it is a book worth to be read. After reading this book I wanted to see the land where the action is supposed to take place. So I spent 3 days in Nordeich last early summer and took the ferry to Norderney through the same channel and the sands which are called "Watt" in German. It was great!
