Within a space opera landscape, Harmony explores the spirituality of a different human culture bound by a rigid caste system. Laudae Sissy, the new High Priestess of the world called Harmony, reaches across all seven castes of her society, seeking a new unity that will protect their isolation from the rest of the galaxy. But other cultures and races are testing their borders, searching for the most valuable commodity in civilized space.

When an alien ship crashes into the space station and diplomatic post Labyrinthe VII, the precarious balance between Harmony's High Preistess Sissy and Confederated Star System Agent Jake begins to dissolve. Suddenly they are caught in a web of deceit and intrigue as undercover agents for both the humans and the aliens vie for control not only of the space station, but of a new and unclaimed planet that may hold the answers many of them seek - or prove to be a deadly trap.
