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. Checkerboard Library; Sharks (ABDO) (4 books by Adam G. Klein) lands at a grades 4–5 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.
