The Last Theorem
Description from the back of the book
A mysterious theorem
In Sri Lanka, a young astronomy student Ranjit Subramanian, becomes obsessed with a three-hundred year old theorem that promises to unlock the secrets of the universe.
Thirty light years away, invisible to human eyes, the Grand Galactics scan the universe for intelligent life. Their mission: to eradicate any advanced species whose technology could threaten their dominance of the universe. Having detected the first nuclear weapons strike on a distant blue plant, a vast fleet of races subservient to the Galactics is dispatched with orders to destroy the warlike aliens.
Condition - good, this is a hardback book - the book jacket shows signs of shelfwear and the pages have yellow aging spot.
