Extinction

So this is a book about a farmer who gets taken by an alien ship to fight a robotic race called the macros. The robots are attacking earth, and can't be stopped by a missile. The man is called John, and he creates a defense force to defend the earth. I really liked this book, since it is my favorite genre (sci-fi). I have read all 4 of the books, and am waiting for the next one to come out. Overall I would give this book 10 out of 10. I would definitely read this again!
