Zander and Felix's relationship has been to the brink and back: the Human-Stin War, imprisonment and an actual death/resurrection. Zander's death, to be specific, and the experience has left him...changed. The mysterious race known as the Guardians chose to revive him and appointed him as their emissary. A high honor, but he could do without the group of would-be cultists following him around the galaxy.

When a recently discovered species destroys a stin probe, Zander's new role soon commands all of his time and focus. The human ambassador—Felix's ex-lover, much to Zander's annoyance—pulls them into strategy talks aimed at preserving galactic peace. Soon everyone is relying on Zander's Guardian tech to telepathically communicate with the strange aliens.

Only Felix seems concerned with the strain piling up on Zander, but he has his own resolve tested when the very stin that imprisoned him show up to a summit. Zander and Felix will both have to find a way to face their doubts and preserve their love—while preventing another galaxy-wide war.
