I must confess, if a book doesn’t hold my interest, I stop reading. I’m limited in how much time I have to read, so I try to read only the best books. Some things that will make me stop reading are:
1. If I can’t connect with the main character
2. Sloppy storytelling/poor writing
3. Plot threads that don’t lead anywhere
4. Meandering plot
6. And this one will cause me to not buy the author’s next book: an ending that wasn’t as phenomenal as the beginning.
How about you? Do you stop reading a book if it doesn't meet your expectations? Do you agree with my list or do you have another list that you'd like to share?
