The Lifeboat at the End of the Universe

As the universe comes to an end around them, the occupants of one lifeboat, part of humanity's last ditch effort to survive the big crunch, finds themselves rocked by a mysterious death.

In a desperate attempt to outrun the Big Crunch and recolonise the resulting new Universe, Humanity sends huge ships stocked with millions of people in hibernation racing at relativistic speeds for the edges of space.
One Lifeboat finds itself in crisis when strange events start to occur and Tom, the crew's Astrophysicist, starts to suspect that all is not quite as it seems or as they have been told.
