I once read a book where it said the wrong character's name after speech bubbles.
I won't have explained that very well but it was pretty embarrassing that the author made the mistake and it wasn't picked up by the editor.
I agree with Booknutt, about repeating phrases and words. It seems when an author finds a word they like they just go with it, over and over again. It's pretty lazy. What makes it worse for me is when I read reviews on GoodReads before I finish the book and somebody has written down my own thoughts and I seem to see it even more.
