The Doom Cloud

A novel for teens. The questions begin when Rob finds the books in the garden. How did they get there? Who is Charlie, and why has he disappeared? Who are the mysterious Watchers, and what the Codifiers up to? And is there any connection between all of this and the Doom Cloud which seems to be increasingly blocking out the sun's light? A fast-moving science fiction story for teenagers, which leads to a meeting with a new giant computer in Canberra and a chase after a gunman - and at the same time raises important life-related questions. Of course, such things couldn't really happen - or could they?
