What Makes This Series Unique?
A Massive 29-Book Arc: From school mishaps to hospital bed escapades, Harold’s world grows with the reader, providing a consistent "mentor" character through the critical middle-grade years.
Educational Integration: Developed by Killara Press, each story is meticulously aligned with Australian and US educational curriculums, making it a "plug-and-play" resource for teachers and homeschoolers.
Beyond the Page: Every book is supported by professional Parent and Educator Guides, bridging the gap between entertaining fiction and actionable life skills like empathy, problem-solving, and emotional regulation.
Perfect for Reluctant Readers: With fast-paced action, relatable humor, and a focus on real-world challenges (like anxiety and social transitions), Harold keeps kids turning pages.
Discover why thousands of readers are following Harold on his quest for a "Hazard-Free" life. Whether you’re a parent looking for a fun bedtime read or an educator seeking quality SEL content, Harold is the perfect companion for the journey.
