The Time Mercenaries

Essef - A story of a sea voyage which ended further away in time and space than any of the crew could have imagined when they set out, and of how a group of 20th century sailors saved a future human race which had become almost unrecognisable... This story starts with a 20th century submarine returning to base and being involved in an incident - at first it appears that they have narrowly avoided a serious collision. The submarine sails back to her home port - but something is not quite right. The first sign that something very strange has happened is that one or two of the older people on board look younger than other crew members remembered them. And the sub's berth at the familiar naval base where they dock seems familiar but the base is strangely quiet, with the minimum of people there to meet them. Not in their wildest dreams could any of them have imagined how far away from home in time or space they really are - or that they will be the only means of defence which mankind has against a ruthless alien invader...
