This is not book one, it is PART one, and not a full story. It's a pity because it did have promise. There are a couple of things that haven't really been explained regarding Mel's background, which made me feel like we'd missed something. Because it's not a full story, it never really goes anywhere or gets a chance to develop.
If there's one thing I particularly hate, it's when a "book" turns out to be merely a part of a story (And nowhere is it mentioned that it's not a full story. It merely says book one in a three-book series. Which is untrue. It's part one of a three-part book, which is not the same thing). I find this sort of nonsense to be manipulative, and I refuse to be manipulated. So, one star from me (honestly, I'd give it zero, if I could), and the author is added to my "never buy again" list.
