At the heart of a bold, growing franchise is Cathy—a passionate life coach, author, and storyteller committed to empowering teens through mystery, moral lessons, and meaningful adventure. Best known for The Obsidian Eye, the first novel in the Sisterhood Sleuths series, Cathy is building a captivating universe that now extends beyond books into apps, games, music, and multilingual experiences.
The Book That Started It All
The Obsidian Eye follows two small-town sisters, Chloe and Lily, from Upland, California, whose world turns upside down when they discover a mysterious artifact. As they follow clues linked to secret societies, ancient history, and local legends, they must rely on new allies—a martial artist, a hacker, and a robotics whiz—while navigating danger and decoding a web of secrets.
With themes of courage, curiosity, and loyalty, the book is perfect for teens who love solving puzzles and immersing themselves in thrilling, character-driven adventures.
A Life Coach Turned Franchise Builder
As a life coach, Cathy brings deep emotional insight and practical wisdom to her stories. Each book in the Sisterhood Sleuths series is crafted to teach key life lessons, including:
- Problem-solving
- Teamwork
- The importance of trust
- Effective communication
Cathy believes stories are one of the most powerful tools to help teens grow intellectually and emotionally—and she’s expanding her storytelling into a full franchise that makes these lessons interactive and accessible to a global audience.
