Query: Chromosome 6

To start with this is the first book I've ever read in the past 15 years. Those who love forensics and medical experimentation will surely love this book. In general you don't need to be a medical expert to be able to follow thesense of the story with all it's medical terms here and there. I am not a medical expert at all. The only thing which I have to criticise is that at times there are so many characters thrown in the story all at once that you start to lose count of who is who. Apart from that the novel is very well presented.
