In the final few years of the 21st century, life in Paris is quiet for Ebriel Serique and her family. They live protected by the glass walls of their skyscraper apartment, safe from the poverty-stricken countries just over the Line of Partition. Until one day, her husband and daughter go sailing, and are murdered by terrorists who claim their yacht had crossed the Line.
Driven by grief and justice, Ebriel ventures beyond the confines of her charmed life to confront the truth about the way the world is run. And while she never would have suspected it, Ebriel discovers that she has the courage for anything-even violence.
