She writes in two directions:
Fiction —The Adventures of Professor Green A humorous mystery-adventure series for ages 12–16, where curiosity, friendship, and imaginative science go hand in hand. Books in the series: The Mystery of Color, Who Turned Off the Lights?, On the Trail of the Mysterious Burglar, and The Secret of the Bubbles.
Nonfiction — Everyone Screams Success Finding Your Own Path in a World Obsessed with Winning — a self-development book about inner balance, clarity, and building a life that feels true without chasing someone else’s definition of success.
The Adventures of Professor Green series is available worldwide in multiple languages.
A gripping tale where science meets adventure. Professor Green and his students uncover the secrets of a mysterious material that could change the world.
Strange power outages strike the academy. Professor Green, Detective Forest, and a group of spirited students begin an investigation that leads them to a secret hidden deep underground. Scientific theories and criminal intrigues intertwine — and unexpected discoveries challenge everything they thought they knew.
Danger calls Professor Green once more. Following the trail of a mysterious burglar, he faces riddles, unexpected twists, and the shadow of an unseen threat.
The Secret of the Bubbles — a city is seized by an unsettling phenomenon that turns everyday life into a scientific mystery. Can the panic be stopped? Who is behind it—and will Professor Green uncover the truth before fear takes over?
This book isn’t about perfect formulas. We’re far too different to live by the same checklist. I see life as something that needs to fit — like a well-tailored piece of clothing. You try it on, adjust it, loosen it where it feels too tight, and add structure where it’s needed.
