The wind has found its voice... and it's calling the Firefly Five.

When a strange golden storm sweeps across Cedar Creek, Sidney, Judy Faye, Kay Beth, Billy Lloyd, and Linda Nell realize the mountain they conquered in their last adventure has awakened something ancient — something that listens. A glowing shard, a sky full of whispers, and a mystery older than the town itself draw them higher than they've ever climbed before — to the top of Windmere Ridge and deep into The Chamber of Air.

But when the wind begins speaking in voices not their own, the friends must work together to solve the riddle left behind by the inventor Amos Cutter — a man whose dream to "teach the sky to sing" may have gone terribly wrong. With danger swirling around them and silence spreading through their town, the Firefly Five must face a new challenge: learning to hear the truth before the world goes quiet forever.

Full of adventure, science, teamwork, and heart, The Whispering Sky takes readers on a soaring journey through mystery and wonder. From stormy mountaintops to glowing caverns, this fifth installment in The Firefly Five Adventures reminds us that real courage isn't found in shouting the loudest... but in listening when the world grows still.
