Liquid Fire is about transforming the human body, and thereby the world. The characters are torn  between two courses of action: passion on the one hand and duty on the other. Their philosophical outlooks of the world are changed based on these actions. Set a hundred years in the future, the world suffers from a dangerous rise in sea levels, and many cities have fallen beneath the waves. Sustainable societies have created new technologies to offset this crisis, including cold water reactors and  dirigibles that glide on the jet streams. Young academy graduates struggle with their developing abilities as a mysterious, technologically advanced intruder attacks their home. Duty will call some to fight; passion will force others to choose a new path.
