Flower Ghosts -- A Flower War Story

In the post-apocalyptic, post-capitalistic future, conflicts between communes are handled via Flower Wars: pretend wars where artists of combat engage in spectacular battles. When ancient machines enter a Flower War uninvited, famous mech pilot Eshe Kollontai decides to follow the trail of a fallen automated border agency, uncovering the ghosts of a long-buried past...and the political machinations of the present.
