The best I could give this poorly written and edited book is two stars. The premise of the story is great. It held great potential for an intriguing mystery with a paranormal flavor. It could have been a really fun read. Unfortunately. after the first few pages, it turned into a mishmash of typos, lack of continuity, with scenes that should have been in one chapter showing up in later chapters out of context. The author switches freely from first person to second or third person. Sometimes in the same sentence. I didn't want to give up on it. I finished it, but the last third of the book was boring.
If this were a work handed in for a college creative writing course I would grade it D, because of the really good story idea, and there was real effort put into the story.
For this author I would tell him to take a few classes, get some first readers and some beta readers who will give him honest criticism to help him with the editing, and reissue the book. It could be good instead of sad.
