Summary: Confusing scientific details, abrupt ending
Review: Normally it only takes me a week to read a Robin Cook book; his writing tends to simplify medical jargon which allows the story to flow quickly. That is, until Chromosome 6. I found it difficult to follow the dialogue relating to DNA and how things related to one another, and for the first time I struggled to finish one of his books. I enjoyed the action sequences, especially at the end, but I did not appreciate the abrupt story ending. If the author is going to write an epilogue reflecting the main characters, he should include all of them.

Summary: The Best Yet
Review: Once again, Robin Cook has shown extreme proficiency in writing his novels. The book was fast-paced, well-written, and extremely insightful about what it means to manipulate our genes with those of another species.Congratulations Robin, you've made me another satisfied customer.

Summary: Where is the ending??
Review: I really enjoyed this book but it ended sort of abruptly. A lot of plot threads were left dangling and I hope that Dr.Cook will write a sequel.I really like the characters of Jack and Laurie and would like to see more plots featuring them in the future.

Summary: This book was interesting and kept you reading to the end.
Review: Chromosome 6 was a pretty good book. It ended sort of abruptly, but otherwise Robin Cook did a great job. He mixed science, mystery, and drama in one storyline. I learned so much about the science aspects of chromosomes and the cloning of people. When you think about the consequences of cloning a person, it blows your mind. I think that the actions of the people where totoally correct. I would do the same. I couldn't beleive when they found out how human the bonobas were, I was amazed that people could actually do that. At the end it sort of just ended without fully explaining about what happened to the main characters. I really wondered about what would happen to the bonobos. Would they be able to survive? Would they leave and join the civilized world? In a way I think he just left it to our imaginations. Overall this book was very good.

Summary: Cook holds his readers until the end....Unfinished?
Review: I am and always will be a Cook fan. I loved Contagion and was thrilled to find the sequal Chromosome 6, until I got to the Epilogue and discovered three of the main characters were left in limbo. Does this mean another sequal? What happened to Kevin, Candace and Melanie....I have been searching the web looking for a Cook site to register a complaint. As an author myself, I cannot fathom such an oversite.

Summary: disturbing to think this could happen!!
Review: I was enthralled by this book from the begining. Being in the medical profession I found it very fascinating and I have to admit I had to read some parts slowly to take in all the medical facts. I often wonder how a lay person reads his books and how they enjoy them. I mostly enjoyed how he carried over characters from one of his other books I felt like I had a head start getting to know the characters. This book held me to the last page. I didn't want it to end. It brought up a lot of ethical questions. I wish he had put the glossary at the begining of the book where I could have used it and not at the end where I found it by mistake. I look forward to his next book I hope he writes forever.

Summary: Sequel, anyone?
Review: The book was interesting and I had gotten to like some of the characters in the previous books. But it does appear the good doctor began to labor towards the end of the book. What happened to the bonobos, Kevin, Melanie and Candace? After getting us interested in all these characters (animals included), we were just left hanging at the end. Does this suggest a sequel? The book was disappointing at the end.

Summary: decent story - unfinished/ disappointing ending
Review: The story is a good read, but it seems Cook was in a hurry to finish the book. The ending seems unappropriately unfinished. The ending is self explanitory, but there are too many story lines in the book are left hanging in the end. I guess it is more important to get a book on the shelves quickly, than to wait and get a GOOD book on the shelves that will keep a reader coming back for more.

Summary: Good
Review: Robin Cook brings his medical expertise to another thriller. The tension never lets up, the plot twists intrigue, and the reader learns while he is entertained. It's almost as good a suspense read as Craig Furnas's "The Shape," for those of you who've read that. I saw Robin Cook talk once, and he says his outlines are about 150 pages long. You can see with the elements he has to bring together in his plots that such outlines are necessary. "Chromosome 6" is an example of such efforts.
