I am trying to slog through this book because I bought it, but I don't like it. Now I am only half way through but that should give me a pretty good idea of the book's content and pace. It seems slow and unrealistic. The part of the beginning about the zoo and his religious experiences held my attention, but since the freighter sank and he explains his experiences on the lifeboat, I have lost interest. I don't know that I will finish the book.
