The only thing it needs to become an amazing book is a good editor, as others have already commented. The story feels refreshing; it is original enough for me to appreciate. Although it does hold elements that may seem to be overused nowadays, such as vampires, these are used well and taken a little further from the cliché. The characters are round enough to be enjoyable.
Again, the problem with this book is the incredible amount of grammatical and orthographic errors. These often caused me confusion, and made me want to stop reading altogether. The book was only saved by its good story, all because the author has great potential; she knows how to engage the reader!
