I really liked this book, good story line, certainly different from most other alien invasion books. BUT large sections of rambling, it may seem like important information to the author, but you'd have to be a scientist to get enough from it. Big words do not make you sound intelligent! Lots of words stuck in randomly all throughout the book that not average everyday words, some are even rarely used.
