Kylie

Kylie lives on board a huge, old, somewhat derelict tanker ship converting to a survivor base, in a post-apocalyptic world after a zombie plague, where remnants of un-infected humanity have retreated unto the water, to the seas and oceans, onto ships and isolated islands, out of reach of the Z-hordes (who cannot swim). On the sea - there are other dangers. Some groups of survivors, initially out of desperation, later - simple greed, evolved into ruthless gangs of pirates, who prey on the poorly armed and otherwise vulnerable. You are on the same old super tanker.
