Publisher’s Blurb – Lower Cover
The order was simple: Nothing to be left alive.

They detected the flash of the first nuclear tests on Earth, even out in deep space. Now sinister intelligences far greater than our own – the Grand Galactics – have assembled a vast invasion force to fly to our planet and exterminate every living thing.

Meanwhile, Ranjit Subramanian, a young Sri Lankan astronomy student, has become obsessed with a three-hundred-year-old mathematics problem. Determined to solve it better and faster than anyone else, his rise to fame draws him into the clutches of a secret weapons project codenamed 'Silent Thunder'.

On the eve of invasion, with China, America and Europe in a final battle for supremacy, Ranjit’s daughter is taken. Now he is all that stands between doom, not only for his own family, but the entire human race . . .
