Pros:* Aliens* Strong plot line* Cool twists and turnsCons:* This is a slow reveal kind of novel* Um Evan's sacrifice??? I picked up this novel because just about everyone I know has it on their to-read list. I was a little hesitant because I'm usually not into sci-fi, but this is done really well. In fact, it really reminded me of [b:I Am Legend|14064|I Am Legend|Richard Matheson|http://d202m5krfqbpi5.cloudfront.net/books/1348790367s/14064.jpg|19273256], which may seem weird that I am comparing a vampire horror novel to an alien sci-fi story, but it is the every man aspect. Yes, when faced with adversity people become strong, but they also make human mistakes and are limited by who they were to begin with. What makes this novel great is that it is about the triumph of the human spirit.In my cons, I do mention that it is a slow reveal. I liked that the plot line was laid out methodically, and information unfolded throughout the novel. There were a few places where I started to get antsy because I wanted details about a wave, or when I had figured out Evan was the silencer and wanted confirmation; but what was great was that these details would come out in the next few pages. It great balance of anticipation and satisfaction.
