What is "adiamante"

Adiamante is a 1996 science fiction novel written by L. E. Modesitt, Jr. It is outside the span of his series work but maintains several of his main themes, including justification of pre-emptive force, nanotechnology, a nearly destroyed but rebuilt Earth, misuse of technology leading to man's downfall, internalized information networks, and shortening or slurring of the names of present-day cities, countries and ethnic groups, along with historical events. For example, a major past conflict in the story was the "SoshWar", a corrupted form of Socialist War.
