Katie and the Hidden Frequency (The Katie Series)

Katie is ten years old, curious, and always listening. When she begins to notice a strange pattern in the sounds around her — a rhythm that feels intentional — Katie can’t shake the feeling that something important is waiting to be understood. With the encouragement of her family, the perspectives of her friends, and her own thoughtful observations, Katie begins exploring the idea of frequency, sound, and connection. Told entirely in Katie’s first-person voice, Katie and the Hidden Frequency blends everyday family life with gentle scientific curiosity and emotional insight. This is not a fast-paced mystery — it’s a thoughtful adventure that invites readers to slow down, wonder, and notice the invisible forces shaping the world around them. Perfect for readers ages 9–12, this story celebrates curiosity, quiet thinking, and the joy of learning — while planting the seed for Katie’s next question about the natural world.
