This is a very short (120 page) action story which was originally written as a free giveaway in Australia as part of a book initiative. It is pretty much non-stop activity as a group of marines land on an aircraft carrier docked at a secret island - and discover they are battling for their lives against unusual opponents.
In such a short book there's little time to develop characters or complex plots. However it should be possible to suck the reader into the story, particularly one so fast-paced. Unfortunately, for this reader at least, the story never really grabbed me, it didn't convince me, and the action sequences felt a bit too unrealistic. It had the feeling of a video game, where people seem able to survive seeming certain death and where they always have the right knowledge and equipment to deal with whatever hazard they face. There is blood and gore and death everywhere, as well as some surprising plot lines where the usual American idea of honour and patriotism are conspicuously absent.
The author also had a very strange tendency to put short phrases in italics which I found a bit odd. I did like the maps, charts, diagrams and drawings of the principal characters scattered throughout the text.
As an introduction to this author's work I suppose this book is good, although it didn't inspire me to read any of his full-length novels. However as a book to encourage people to read who are perhaps put off by longer stories and who like this kind of writing I think it's a great option.
