Doctor Who: Scales of Injustice by Gary Russell - The Worst Thing About it

So, I have recently begun to read the book Doctor Who: Scales of Injustice by Gary Russell, and thus far it has not succeeded in catching my attention. I am usually a very avid reader, especially when the book in question is a Doctor Who book, but so far I have not enjoyed this book that much. This led me to wonder: why aren't I enjoying it? Or, in other words, what is the worst thing about this book?

Upon reflection, I decided that I knew what the worst thing about this book is. I am 18% of the way throught the book, and still there has not been much action, nor much of a plot. So basically, there is nothing so far that draws me in, makes me want to know what is going to happen next, nothing that really makes me care that much about what happens to the characters. Sure there have been several scenes with some action where someone dies, but each time it has been a minor character and there has been no further elaboration about how it was important to the rest of the story. Everything is just sort of disjointed. THAT is why I am not enjoying the book. It does not have any substance.

I will keep reading and hope that it improves, but if it does not, then I might have to just quit reading it. That would make this book one of only 2 Doctor Who book that I could not finish. But lets hope that doesn't happen.
