I'm a big fan of [b:Infected|2331954|Infected (Infected, #1)|Scott Sigler|https://d202m5krfqbpi5.cloudfront.net/books/1388298775s/2331954.jpg|2338528] and I thought the sequel was pretty good too but this third one took a dive. A little on the slow side with too much medical mumbo jumbo. Sometimes it was like reading a biology textbook.
