When a US survey team investigate an area where there is no ice, despite being in the Antarctic, they find more than they bargained for. It could be evidence of global warming gone wild, but the manufactured objects in a newly defrosted crater suggest otherwise. At the same time a deep space observatory detects puzzling bodies entering the solar system. Are they simply uncharted comets or something much more dangerous? Meanwhile 16-year-old gamer, Josh, is starting his new year at high school, when a summons to the principal's office opens up a whole new world for him, encouraging him to join the school's programme for outstanding students. Soon he has a duplicate, a role in a secret Deep Space organisation and a whole new set of problems. The secretive surveillance team outside are concerned about activities at the school. The astronomers have their doubts about the objects heading for Earth. The military are worried about invasion. Which 'Josh' is actually at school? Who are the mysterious others and who exactly is controlling it all?
