Infected, Contagious and Ancestor - books 55-57

Infected, Contagious and Ancestor are three books by Scott Sigler. I found them all unputdownable. Infected deals with a situation where "a number of unlucky humans ... develop some unusual symptoms—itchy, blue triangular growths on their skin—that eventually result in the carriers becoming screaming, homicidal maniacs" (Publishers Weekly).   Contagious is its equally riveting sequel. In contrast, Ancestor is about what happens when scientists try to play God, creating a throwback that could kill them all. Part medical and scientific thriller, part horror story, all three novels grip you from page one. I'm not a big horror fan, but found that in most cases, there was less gore than suspense (though there were some creative ends for some of the characters). Collectively, I give these books 4 stars.
