Sitting in a coffee shop, eyeing the human he's there to help—Charles—Mordecai listens to the man's internal troubles so he can discern the best way to assist him. Mordecai hears Charles wondering why he's agreed to meet his workout buddy, Jeffrey, for coffee...knowing Jeffrey intends it as a date.

Everything changes when Mordecai gets his first look at Jeffrey and meets the man's gaze. The human, Jeffrey—Charles's date—is his stella guida, his guiding star—the one human he can share a soul with. How can Mordecai help Charles come to grips with dating Jeffrey, when every instinct screams at him to take him for his own?
