Little Maeve loved the big willow tree by the stream. Its long, green branches tickled her nose when the wind blew. Swish, swish, swish went the leaves, like a gentle song.

Maeve would sit beneath its shade for hours. She loved listening to the stream go gurgle, gurgle, splash as it danced over the smooth stones.

One sunny afternoon, Maeve heard a tiny whisper. 'Psst! Over here!' It wasn't the wind, and it wasn't the stream. Maeve looked around, her eyes wide with surprise.

Maeve peeked closer at a knot in the bark. Tucked inside was a tiny, sparkling sprite named Faelan, no bigger than her thumb, with wings that shimmered like jewels.

Faelan was the guardian of the willow, but she had lost her special singing stone. It was a smooth, grey pebble that made the willow's leaves whisper happy tunes.

Without the stone, the willow was sad. Its leaves no longer sang joyful melodies; they only rustled with a soft, lonely sigh that made Maeve feel sad too.

Maeve promised to help. She carefully searched the soft earth around the willow's roots, feeling under fallen leaves and beside the smooth river stones.

Tap, tap, tap went her fingers. Then, she spotted it! A small, grey, smooth stone was tucked between two roots, feeling warm from the sun.

Faelan chirped with delight as Maeve returned the stone. Instantly, the willow tree sighed with happiness, and its leaves began to sing a joyful melody on the breeze.

Maeve smiled as the tree danced. Faelan gave her a tiny, sparkling wink before disappearing back into the willow's heart. The secret of the willow was safe with Maeve.
