In my book, I start out by introducing the main character, her uncle, and her mother in one scene. The next scene involves her grandparents, and the next is about five more characters after that. The first two scenes are in one chapter, but the five new characters are in the next. How do I know if this is too many characters introduced at once?
I've heard that you shouldn't introduce too many characters all at once, and I'm not sure if this falls into that category. Does this advice mean not to introduce ten characters in one scene, or does it mean over an extended period of time? If it means over an extended period of time, I'm not sure if I fall into that category or not.
For reference, my genre is YA fantasy and this is the first novel I've written.
