Most of my chapters wrap up with unanswered questions. To me that's good. It's intentional. It lets the reader be curious about things and want to find out more. Sometimes these questions are answered in the first paragraph of the next chapter, other times the answer is several chapters away. I've had more than one person read chapters of my WIP and complain about not having something explained to them. Am I wrong? Or is it good they have these questions?
