Hell Island was released in 2005 as part of the Books Alive promotion – the only way to get it at the time was to buy another Australian book in order to receive it for free. Given Matthew Reilly’s popularity at the time, it was a brilliant idea. People (including me) were desperate to get their hands on it. (I bought a Phryne Fisher book by Kerry Greenwood – didn’t like it but love the TV series that is based on the book series.) That was when I first read it.
The story is part of the Shane Schofield narrative, Reilly’s heroic US Marine who always seems a little smarter, a little stronger, a little more strategic than everyone else around him and one hell of a survivalist. In the Schofield chronology, it takes place after Scarecrow and before Scarecrow and the Army of Thieves but is easily removed from it. And enough is regurgitated to make this a stand-alone book.
