This is the eighth and final book in the Vikram-Aditya series and the second of the two-part 'Andaman Adventure' books after The Jarawa.

When the book begins, Vikram, Aditya and Chitra are in Port Blair, the capital city of the Andamans. The trio are recuperating from their recent adventure in the remote Jarawa Jungles in the Andaman Islands. While exploring this colourful city, Vikram stumbles upon a series of intriguing clues. However, the investigations he conducts end up ruffling some feathers and manage to upset some powerful criminals. To escape their wrath, Vikram is forced to undertake a secret voyage destined for unknown shores, under cover of darkness.

In the remote corners of the Andaman Sea lies an island called Barren. Vikram arrives at this uninhabited and forgotten outpost of India, and soon discovers that it is not just a band of desperate men he must pit his wits against. Primal forces of nature, the very ones that shaped our planet, are at work on Barren Island, and Vikram and his companions have to face these challenges as well. Finally, this scintillating adventure series comes to a fiery and exhilarating climax on Barren Island's isolated shores
