Icky, Sticky, Gross-Out Books Books in Order

4 books by Pam Rosenberg. Reading level: Grades 4.8–5.4. 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. Icky, Sticky, Gross-Out Books (4 books by Pam Rosenberg) lands at reading level Grades 4.8–5.4, with average content intensity 1/5. Intensity stays consistent across the series — a kid who can handle the first book can generally handle the rest.

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.
