And then there is the biography, Savage To Saint,
probably because it was the first English language biography of Karl
May. One of the more unusual favourites is the pirate tale of Captured at Sea, in which Winnetou visits Germany for the first time.
The Travels of Winnetou & Shatterhand (Satan & Iscariot) because of the missing romance part ... and Old Shatterhand-Genesis ...
But while these seven books readily jump out as equally memorable, so does every one of the Adventure Novels, and every one of the Travel Fiction Novels.
In the end, and because of the unusual circumstances of the creative processes involved, I must admit that the 2012 Anniversary Edition of The Treasure In Silver-Lake, and Out of Vandaemonia are my equal favourites of the splendid collection of books.
