I just received my book from an editor. It turned out that the majority of my story did not sound believable at all. I've had this problem for a while, and yes, I did read a lot of middle grade novels before I started writing this. Now I have to change the story to make it sound believable. I have some ideas planted in mind, but it's still too early to rush it. I am also taking a psychology course at my college, but I don't think that'll help me with my story. Did anyone ever get frustrated over their long-term weaknesses before, because I got the "wrong" message that my book is just slush.
