There are three rules Wynne must abide to:
One: Love no one.
Two: Be an invisible force.
Three: Kill all, who know your face.
Yet, even after years have passed, people come looking for Wynne. And when Wynne runs into Klement and Illias—two handsome young men who make Wynne want to trust again—it becomes increasingly harder for Wynne to keep the vows he made, when first accepting his job as an assassin, for it would mean having to kill both the men he has fallen for, when all he wants to do is stay with them forever.
