I found this book when searching for medical thrillers on Amazon. The premise sounded interesting, so I decided to give it a shot (independent author). I'd say it's more of a scientific thriller than medical, even though it involves a virus, or rather, retrovirus.
The pacing was pretty quick, and the story kept me on my toes as it shifted from one character to another. I thoroughly enjoyed it. All in all, if you like a good medical / scientific thriller, then you should give this independent author a read!
