Third grader Nilo Rivers clings to his sketchpad for comfort—until the pad itself sparks an invitation to the mythical Melody Mountains. Under the guidance of eccentric Maestro Arden Seba, Nilo teams up with Mira, a log-tapping percussion genius, and Corin, a fearless drum-carving sculptor, for a grand expedition where paintbrushes behave like drumsticks and canvases hum basslines. Each chapter doubles as an immersive art-and-music workshop, teaching young readers about hue mixing, brushwork, texture, and rhythm. When a mysterious silence falls over the Echo Cavern, Nilo discovers that only his watercolor sketches, powered by collective drumming, can restore the mountain’s hidden murals and his own shy voice.
