Operation Stargazer — Chris Hawley

Bill Steadman and his friends may still be average teenagers, but now the grave responsibility of saving Planet Earth has landed squarely on their young shoulders. Operation Stargazer is the sequel to Secret of the Red Planet, and the second book in The Mars Series. It tells how Bill and Sonia, together with their friends, Ben and Tim, involve themselves in the battle to save Mars from Zigismo, the evil dictator of Zeronera, who is intent on enslaving the inhabitants of the Red Planet. And other challenges await them. The Zoggs, a race of strange beings from another solar system, aim to use Zigismo to conquer Mars and use it as a springboard to attack our own beautiful planet. And the ultimate adversity; a huge, dark and dreadful asteroid is reported to be on a collision course with the Earth. It is a race against time for Hermann Winke and the Russian scientists to perfect the technology, the only technology that is capable of dealing with the monster that threatens to blow the Earth to pieces.
