Here to There — Jane M. Lindskold

Captain “Allie” Ah-Lee of the single-ship Mercury finds herself reluctantly recruited to take part in what, on the surface, is just a light-hearted adventure contest. Her real task is to find the saboteur who is out to undermine the game – and so bring catastrophe down on the entire human race. Can Allie unmask the saboteur before the saboteur unmasks the hidden violence of the human soul?
