It has since grown into an eight-book franchise with a free digital magazine, a global schools outreach programme, a podcast, original music, and board games in three languages. All of it is aimed at the same audience: readers aged 10 to 18. ### Book: The Obsidian Eye *A Young Adult Mystery Thriller* By Cathy Warshaw When sisters Chloe and Lily from Upland, California discover a cryptic artifact called the Obsidian Eye, their small-town lives erupt into a race against time. As they unravel clues tied to secret societies, ancient mysteries, and local legends, danger lurks at every turn. With help from a martial artist, a hacker, and a robotics genius, the sisters’ courage and bond are pushed to the limit. The first book in the eight-part Secret Societies and the Sisterhood Sleuths series. [Amazon (Kindle)](https://www.amazon.com/Obsidian-Eye-Thriller-Societies-Sisterhood-ebook/dp/B0F49FZZ2X) Warshaw, an award-winning author and certified life coach based in Upland, California, has structured the franchise so that each component feeds the others. The books supply the narrative. The magazine gives young readers a place to contribute their own work. The outreach programme brings the material into classrooms. The shared premise is that mystery and investigative thinking can teach teenagers confidence, teamwork, and critical reasoning. ## What the Sisterhood Sleuths Young Adult Mystery Series Covers The eight books follow an international team of young investigators working through mysteries set across multiple countries. Locations include the Swiss Alps, the Louvre, ancient catacombs, and Celtic landscapes. The titles run from The Obsidian Eye through The Land of Promise, The Swiss Enigma, Whispers in the Catacombs, The Louvre Enigma, The Celtic Mask, The Northern Code, and The Dragon's Awakening. Each book is paired with original music, puzzles, ciphers, and interactive challenges that extend the reading experience beyond the page. Other [children's book authors have used fiction as a teaching tool](https://richbooksmagazine.com/article/sharon-philbrick-created-a-children-s-book-series-that-teaches-economics-without-a-single-lesson), but the Sisterhood Sleuths series is unusual in pairing each title with its own soundtrack and cipher set. The series tagline, "Secrets are everywhere. Curiosity is the key," sets the tone for the broader franchise. ## How the Free Digital Magazine for Teens Works [Sisterhood Sleuths Magazine](https://www.sisterhoodsleuths.net/magazine) launched on 20 May 2026 as a free monthly digital publication. It is open to readers of all ages but targets the 10 to 18 bracket. Each issue includes mystery-focused articles, interactive puzzles and cipher challenges, cultural narratives from international contributors, and profiles of teenagers making a measurable difference in their communities. Programmes such as [youth film festivals](https://richbooksmagazine.com/article/youth-film-festivals-cultivate-the-next-generation-of-creative-voices) have shown that giving young people a creative platform can build skills that formal education often misses. The magazine also publishes creative writing and essays submitted by young readers, making it a participatory platform rather than a one-way publication. The free model is a conscious choice. Warshaw has removed cost barriers entirely, allowing schools, libraries, and individual readers to access every issue without a subscription fee. ## How the Youth Outreach Programme Reaches Schools and Libraries The Sisterhood Sleuths Outreach Programme is an international educational initiative that uses the book series as a teaching framework. It is available to schools, libraries, homeschool groups, and youth organisations at no cost. The programme combines social-emotional learning with puzzle-based problem solving and creative writing exercises. Students work through mystery scenarios drawn from the books, developing skills in collaboration, leadership, and analytical thinking. The curriculum is designed around The Obsidian Eye as the entry point, with activities scaled for different age groups within the 10-and-older range. Warshaw positions the programme as a practical application of the fiction. The same investigative mindset that drives the book characters is used as a pedagogical tool in classrooms and after-school settings. ## What Comes Next for the Sisterhood Sleuths Franchise The franchise continues to add formats. A podcast is already live, and a mobile app is in development that will offer interactive storytelling, puzzles, and bonus content. Board games based on the book series are being launched in three languages. Warshaw operates the franchise through C&B Creative Partners LLC and is a member of the Alliance of Independent Authors. She lives in Upland, California, with her husband Brian and their two dogs, Charlie and Bailey. **About Cathy Warshaw** Award-winning author, songwriter, and certified life coach who created the eight-book Sisterhood Sleuths mystery series and its associated free digital magazine and global youth outreach programme.
