I want to start by pointing you back to the source itself, Miss Mason's Volumes. Although she writes quite a bit about narration by making reference to it in small ways throughout the Volumes, these are the main sections which cover narration. Then, I will give you my favorite Parents’ Review Articles. Finally, I will share my favorite blogs and websites.
