Follow up to Sigler's Infection. Concludes the story of Perry Dawsey, Dew Phillips, and Dr. Margaret Montoya and the Triangle infection. A very good read, but a strong stomach is required for some of the more intense scenes. I listened Infection on Book Radio and just felt compelled to read Contagious and see it through to the end. I was not disappointed. Sigler moves the story along at a quick pace, not giving the reader time to get bored with the story.
