Jonathan Bartell is a young man, just out of university, when he signs up for the position of Quarantine Officer at the Orbital Launch Station.
He is part of a crop of students who flocked to study exo-biology when bacteria were discovered on Mars, and who are now all making their living flipping burgers, because the jobs are few and hard to get.
He is lucky to get a job in space, no matter how mundane.
Or so he thinks...
Gaby Larsen is a doctor at the tiny hospital at the space station, and she keeps secrets, not because she wants to keep them, but because she is too scared to share them.
Because out in space, your worst enemies are your fellow travellers.
