About the author
Loxley Browne
11 booksLoxley Browne is the real-life embodiment of a modern-day Renaissance woman — equal parts designer, adventurer, and dream builder. With her trademark curiosity and can-do spirit, she’s spent decades exploring the intersection of creativity and character — from London Museums to the Himalayan mountains of Nepal, from bulldozers to book tours.
As the founder of Athenian, an award-winning STREAM edu-tainment nonprofit, Loxley has inspired thousands of students to dream boldly and build fearlessly. Her mission: to help the next generation take the wheel of their own learning, armed with confidence, curiosity, and character.
With the Charms Book Series — and the companion journals, workbooks, downloads, and merch — Loxley created the kind of immersive experience her younger self desperately needed. She believes education shouldn’t be something that happens to students, but something they take charge of. Through Attie McAllister — a 15-year-old inventor navigating friendship, curiosity, and courage — readers learn that leading with character and a moral compass isn’t old-fashioned; it’s revolutionary.
“I was lucky to grow up with a mix of farm-girl grit and city-girl spark,” says Loxley. “That balance, strengthened by my years in 4-H, taught me leadership, responsibility, and the importance of leaving a place better than I found it.”
With the option to purchase your Charms book as an eBook, paperback, or hardcover — and pair it with the Inventor Notebook, Charms Journal, Future Me Workbook, and the Secret Book Society — readers can dive deeper into Attie’s world and build real-world skills along the way.
