I finished the book but admit to doing a lot of skimming. The story is unbelievable. I did not appreciate the graphic violence. The main character is an utterly irresponsible father, which made me dislike him. The happenings on the Island are just weird--felt like it was trumped up sensationalism. To me the book, starting with the main character's researcher, displayed sadism. It may be one of the worst books I have ever read. The plot was not thought out, the action rushed, the son's mother dealt with "painfully". Ugh! I will not read another Peter Benchley.
