Forbidden Island has got all the elements of a great adventure story -- sparring characters, intensifying mystery, sudden and compelling danger, help from an unlikely source, and something of a twist at the end. But all these elements have been arranged very neatly in a row, and the story plays from scene to scene like a video game. The author telegraphs everything in advance, and over-explains once it has happened, so -- despite the large print and no more than 200 words on a page -- the story always seems to be lagging behind itself. Even in the middle of the action, I felt like yelling 'get to the action!' Ultimately, we run out of book, and there is no more action, and it feels like, somehow, there really never was.
I used to read books like this out of the school cupboard when I was nine, which is probably the lower end of the age range this book is aimed at, though the main characters are secondary school age. At that age, every book was a small adventure, and I tore through them voraciously. But, even at the age of nine, I realised that some adventures were better than others, and some books had the power to call you back to them, whereas others seemed to be written to be discarded.
I'm really sorry to have to say this about a book by a prolific author who clearly has quite a following, but this (at that age) would have come into the category of 'read and forget'. The writing style is at the same time boring _and_ skittish, jumping around even in the same scene between danger and unconnected banter. The constant over-explanation (in my opinion, and, of course I am no longer a child, and was never 'every' child) would make most children feel they were being talked down to. The characters are not especially engaging, and certainly not particularly memorable. What's more, the references to MI5 and the press are just too unsophisticated for a generation that was brought up on new-style Doctor Who, Torchwood (if up late) and Spooks (also if up late).
So, where am I going with this? If you're nine, and can never get enough of books, you'll probably sail through this one, enjoy it as you would enjoy the demo-level of a fairly easy video game, and then go on to something else. No problem with that. But if you're a fairly slow reader, the pay-off in terms of excitement isn't that great for the amount of concentrating you have to do.
I probably won't be recommending this one.
My apologies to everyone who liked it, and to the author.
