Thicker than Blood [Short Story]

Cliona is a vampire, though she has adapted to ocean life rather than prey on human blood. Centuries later, she finds that her new home is being destroyed, as humans begin to exploit the power of the ocean as a cheap source of energy to fuel endless wars. Cliona decides to take on the main profiteer-her brother, the man who made her a vampire. This is a side-story to the Hibernia Altera sequence, set in the Outland, and is included in the collection Fluctuation in Disorder.
