David Webers Out of the Dark is a wonderful book. I didn’t think so at first. In fact a bit over halfway through it I was getting upset because it looked as if there was no way at all that the earth was going to survive. They have been invaded by aliens with a superior technology. Then he comes out with a huge surprise. Something completely unexpected. It was a great way to end the story. You should read it!!
You can get a copy of Out of the Dark at Barnes and Noble.
