I recently read the book "Invasion" by J. S. Lewis. This book was provided free by Booksneeze.com in exchange for my review.
I originally selected this book because the cover had an interesting Sci-fi look to it, plus the title alludes to the fact that the book would have aliens or other "out-of-this-world" characters. The story consists of 57 relatively short chapters, typical of a young adult novel, and is an easy read.
I compare this book to the movie "Men In Black", as it follows the same type of story line - aliens, shape-shifters, and other creatures hidden amongst the human race, and of course, there is a conspiracy.
This book has plenty of action, including flying motorcycles, secret gateways, and of course government cover-ups, which I think would keep a teenager who is into Sci-fi interested in the book. I do think it is unfortunate that this book is part of a series (C.H.A.O.S.) by the author and the next installation is not due to come out until January 2012.
My only disappointment in the book was its lack of character development. It was easy to pick out the main players - Colt, Dani, and Oz - however I didn't feel like I could get into their heads. The story was slow but I think it is leaving room for the rest of the series.
