I will admit I was reluctant since this only the unfinished beginning of a book Burroughs put up on the shelf. But having just read the Venus series as free ebooks I couldn't resist. It was very good and happy that even unfinished it was published. My biggest surprise was the add on Pirate Blood. Nothing to do with Carson of Venus and at first I wasn't even going to read it but it was suprisingly good. I would recomend to any Burroughs or pulp fan.
