There is nothing spectacular about this book. It is a good, solid story that introduces the main characters that will no doubt fill the remaining two books. Some of the ideas introduced by the authors to explain the appearance of aliens on Earth are quite clever and draw on actual historical events, which I found quite interesting.
There is plenty of action here for the action junkie but it is a little lacking in shall we say sci-fi diversity. The technology, although superior to human technology, is still similar in many ways to that used on earth. The aliens, although somewhat different in looks and especially breathing capabilities are still mainly hominid in appearance and stand on walk on two legs just like humans. That being said, the story was more one of the indomitable human spirit and the power of organised resistance even in the face of overwhelming odds. Just for kicks, there's also some developing love stories burgeoning, which I'm sure will be expanded on in the future books.
The end had the necessary ingredients to set the scene for the next book, which is always important. I enjoyed the read - it didn't take too much brain power, like some sci-fi novels do. All in all, a nice, straightforward and easy to read book and at 360 odd pages, plenty to get your teeth into,
Will I buy the second book in the series - quite possibly. I liked the style and the story. Well worth its four stars.
