Series Description: The Misadventures of Hazardous Harold

Join Harold on an epic, 29-book journey through the messy, hilarious, and ultimately rewarding world of growing up.

The Misadventures of Hazardous Harold is more than just a book series—it’s a comprehensive Social-Emotional Learning (SEL) ecosystem designed for readers aged 8–15. Through the eyes of Harold, a well-meaning but disaster-prone protagonist, children explore the ups and downs of life, learning that mistakes aren't failures—they are the first step toward resilience.

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.
