By the brook, the friends hear a new kind of water—a whisper that isn't their usual splash. They follow the sound and build a fern-leaf sound map: a pebble for home, a grass blade for the gurgle under roots, tiny seeds for the drip at the mossy wall, soft moss for the waterfall's rush—until a white blossom marks the clear song of the spring at the heart of the forest. Beyond the ferns a secret glade opens: in a bowl of bright pebbles the spring bubbles quietly, as if telling an old story. Listening closely brings calm—and shows the way back. Step by step, the same sounds guide them home: drip, gurgle, splash—their brook again. This picture book blends gentle suspense with clear, soothing language. Each spread offers short read-aloud texts and rich details—ideal for bedtime and first reading steps. Extra: Heart-Quest! On every illustrated spread, 2–3 tiny hearts are hidden—search, count, compare. No scare factor.
