The Secret of the Nagas is the second book of Amish Tripathi, second book of Amishverse, and also the second book of Shiva Trilogy. The story takes place in the imaginary land of Meluha and narrates how the inhabitants of that land are saved from their wars by a nomad named Shiva. It begins from where its predecessor, The Immortals of Meluha, left off, with Shiva trying to save Sati from the invading Naga. Later Shiva takes his troop of soldiers and travels far east to the land of Branga, where he wishes to find a clue to reach the Naga people. Shiva also learns that Sati's first child is still alive, as well as her twin sister. His journey ultimately leads him to the Naga capital of Panchavati, where he finds a surprise waiting for him.
