This is one of the best books and I will tell you why. This is a story of Kaalkoot which is a poison that can strike and bring down the whole world in a single swing. And this story has both good guys and bad guys like every other story has. So these bad guys got hold of Kaalkoot using their manpower but can't find an antidote to protect them while they destroy others because they haven't got the scientist's brain. On the other hand, our good guys know where the antidote is and by finding it, they can save the whole world from destruction. But finding it is not easy because a long forgotten and not so famous smart guy had hidden it inside a cave and let only riddles and clues behind. So now these good guys have to find it or the destruction will be enormous. It's not just that, it's a story of a guy who is ready go to the centre of the earth to find his girlfriend. And by doing so, he also caught up between these two gangs. He has to choose a path or he will lose his girlfriend.

The story was full of action packed, mystery, and science. But you will see more thugs than science. It was a fast paced thriller which can be read even in a single sitting irrespective of the number of pages. The plot happened in two different timelines but the writing and editing was very clear so that we could never get confused anywhere. And now for a bonus point, we also have a strong independent woman as a secret agent who will risk anything to achieve what she wants. It also reminded me of Dan Brown's plots but it still had some different elements in it. The writing style was really smooth and it didn't falter anywhere. That was awesome. I really enjoyed reading it a lot. And I would definitely recommend it to everyone here who is a fan of good mystery thrillers.

(0.5 is missing because I wanted more of that female secret agent. I wanted more action from her)
