Content Intensity Across the Series
ConsistentContent stays at a steady intensity level throughout the series.
Series books grow with readers — but that's also the trap. Most series start at one reading level and one content intensity and drift upward over the course of the run. True Book: National Parks (6 books by Josh Gregory) lands at a grades 5–6 reading level, with average content intensity 1/5. Intensity stays consistent across the series, so a reader who can handle the first book can generally handle the rest.
