Adventure books, I keep reminding myself, were written in the mid-1970s for men, just as James Bond movies were made for men. And the women in them are, well, less than the men. If you can make it past this issue, the book is a fun, quick read.
Dirk Pitt goes to look at a ship stuck in an Iceberg, and has at least 3 attempts at his life because of something he has learned, but he doesn't know exactly what. As with Sahara, which was recently made into a movie, the actions sequences are improbable, but fun. An enjoyable read, if you ignore the women!
