I was deeply disapointed by this book. I have seen the movie and it is much better. This book is very wrong and gives sharks a negative picture. Sharks are very rarely known to eat humans, in fact, you are more at risk of getting struck by lightning than by getting eaten by a shark. When sharks do attack humans it is mostly because they have been confused and have mistaken you for other prey. This is why after the shark bites it usually swims away.When people look at the cover of the book, they might think that it will be about a shark who goes on a killing rampage, but the book is not mainly about the shark, most of it is about a lady who wants to get sexually involved (for some unknown reason) to a man other than her husband. This takes away from the excitement and is very boring to read. The conclusion is also very bad because it doesn't end with a sense of finality. It just ends when the shark eats a man and another man that was on the boat with him swims to shore.
