A Mammoth Problem

Things are getting hairy. The Mammoths are returning whether we want them or not. The engineering team sent to maintain the Ice Age is running a little late. Okay ten thousand years late due to the wrong type of asteroid but our planet is important to them and will be frozen as soon as mechanically possible. When Eric Patterson's Mum takes in an alien created purely to take the temperature of planets who is on the run from the Government he doesn't realise they have a day to save the world. With the Russians, Americans and Belgians after them things are about to get very hairy indeed
