I've managed to mire myself in an annoying problem. I recently began work on a series of books set in a fantasy world. The third book is the furthest along, and I've written that my protagonist, a human female, has become the ruler of a race of mountain-dwelling humanoids. It all sounded great until I realized that my first book is intended to be the story of a woman who inherits the throne of a human country from her grandmother. Are these plotlines going to clash with the reader? If so, how do I avoid it?
