I read here that someone wanted Robin Cook's novel that has some interesting
microbiology in the plot... the title is Chromosome 6.. most people complain
that there is too much science and not enough novel.. I liked it.. the science
(and ethics) get you thinking.
The audio book is up for auction on ebay..
