In a kaleidoscopic underwater world, blue whales Crescendo and Echo, joined by quirky marine friends, witness their fragile home ravaged by fishing and seismic testing. With mounting peril, mistrust of humans, and time running out, these ocean dwellers unleash creativity and courage, hoping to spark the compassion of researchers above.Comedic misadventures and poignant moments blend as the creatures orchestrate a spectacular broadcast, warning the world of their plight. Their efforts ripple globally, inspiring humanity to reevaluate its relationship with the sea. What begins as a skirmish for survival swells into a triumphant, global call to environmental action.(Received the Literary Titan Gold Book Award 2026 in the Children’s Books genre.) 6
