Query: Disappointing

Although the subject matter of this book, in-vetro fertilization and the corruption of the experimental fertilization industry, is highly interesting and controversial, the book itself was a disappointment. Cook could have done so much more with such engaging and timely subject matter, yet contrary to the reviews provided on the book's back cover, the story is NOT believable (great white shark attack, Hong Kong mafia, and illegal smuggling of Chinese Buddhist monks into Australia). I found that the book was drawn out with unnecessary and boring descriptions, and plot tangents that had nothing to do with the story itself. Although it keeps the reader in mild suspense until the last pages, I thought the ending was predictable and not interesting enough to justify the time I spent to finish it. I write this review to help save others from wasting time on an only semi-interesting book. Try another of Cook's medical thrillers, this one is unfortunately a flop.
