Pandemic by Scott Sigler
This is the conclusion of the Infected Trilogy and this is one of those rare trilogies where it ends almost as well as it began. In my mind Sigler can never top the awesomeness of the first book, Infected, probably one of the best horror books I’ve ever read (just say “blue triangle” to me and I still shiver), but he came close.
It’s been a few years since Detroit was wiped off the map to keep the alien invasion at bay but not everything has been destroyed. A small canister is discovered on the bottom of Lake Michigan and what it contains may possibly destroy the entire human race. If the aliens don’t wipe us out, our reactions to the contagions probably will.
A great world almost-ending book showing how events could possibly play out on a global scale; the psychology of the world politics is really interesting. The first book is about an inner struggle with an infection, the second involves an entire city and the third the world. It’s an interesting study in human interaction and contagion vectors. The later hopefully being something we’ll never need to know anything about! I highly recommend reading these in order for the full impact of the tale.
