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. Exploring Habitats (Fitzgerald Books) (4 books by Ted O'Hare) lands at a grades 2–3 reading level, with average content intensity 1.3/5. Intensity stays consistent across the series, so a reader who can handle the first book can generally handle the rest.
