Watts Library Books in Order

9 books by Anthony D. Fredericks. Reading level: Grades 6.5–7.4. Middle Grades (Ages 9–12).

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. Watts Library (9 books by Anthony D. Fredericks) lands at reading level Grades 6.5–7.4, with average content intensity 1.3/5.

The reading-order table below lists every book with per-volume reading level and intensity badges so you can spot any escalation before it catches your reader off guard. For a deeper dive into how we score text difficulty vs. emotional weight separately — and why series readers especially benefit from that split — see our methodology page.
