Somewhere in the Kaveri River where the water rushes through a deep gorge, lives a very special fish called Matisha, one of the largest and most beautiful freshwater fish on Planet Earth.

Matisha delights in exploring her mysterious underwater world and meets a vast array of magnificent animals with whom she shares the river and the surrounding jungle. She is fascinated by the many strange fish of all shapes and sizes and the large powerful animals like tigers and elephants which occasionally visit the river. She dodges the attention of hungry birds, crocodiles and otters who would love to gulp her down as prey. She also learns about humans, who are sometimes far more dangerous than the animals around her.

In this dream-like story, follow the wonderful adventures of Matisha as she migrates upstream to lay her precious eggs. Illustrated beautifully by Maya Ramaswamy with vibrant colours, the invisible world that lives below the waters of the river and in the Western Ghats comes alive through the eyes of a fascinatingly beautiful, yet critically endangered species.
