Think of this, the world has become too hot heat waves following heat surges. People leaving their cars succumbing of thirst waiting for the coolness of evening that will not come. The stench of dead humanity and animals are foul of decay. On the highest building a man fine tinned food, eats and falls asleep and wake up months later to a world where he is the only survivor. No lift he walks down the endlessness of stairs and is met with a hush so loud he has to put his hands to his ears. He walks and walks the stink has gone, but he senses something behind him it is a lone rat it is as confused as he is and together with the rat on his shoulder, they begin the search to find a mate to make the world inhabitable again.
