Lilith: A Snake in the Grass

"Book One of The Four Lords of the Diamond" introduces a story where aliens monitor Earth from one of four worlds within the Warden Diamond, with traditional agents unable to visit due to microscopic symbionts. Instead, each world receives a stripped-down individual controlled by Confederacy operatives, including Cal Tremon on Lilith, who faces dangerous challenges both on the alien planet and under the influence of his controllers.
