I had almost zero expectations going into reading this book other than that Michael Crighton is a great writer and I enjoyed Congo a lot and I enjoyed the Jurassic Park movies. I could tell that it was about some kind of virus as the term "strain" usually means something bad and biological and there are lots of strains of viruses and viruses are on the mind of late. Based on the previous titles I was expecting some kind of action-adventure story but that is not what I found with this book. Instead, I was slowly taken on a cerebral journey through a subtle world of science fiction in a way that I haven't experienced before.
