This book is misleading in a sense because it promises to be a 'choose your own adventure' story and that is of course, nonsensical. All you get to do in this case is to choose is one of two options presented by the author, so it's really a choose his own adventure story. It's middle-grade and the plot is about some stolen crown jewels.
I should say right up front that I haven't had any success with novels by this author. In the middle of June 2015, I reviewed The Mystery of Adventure Island and The Mystery of Smugglers Cove and I hadn't liked either of them. I therefore knew going in that I probably wouldn't like this one either, but I was still curious to see how this story worked. The short answer to that is that it didn't! And I mean that literally.
I read the first section and tapped on the link that was supposed to take me to my chosen option, and nothing happened! I tapped on the other link, again without result. None of the links worked which makes this book a waste of money! I actively dis-commend it.
