Yna must take her sister's place in the diplomacy between Men and Nature, after her sister's relationship with the Prince, Ergo, is betrayed.
She is alerted by her Kin that there is an evil that preys on the souls of Men in the in-between, the place just beyond the veil that rides the border of life and death.
Yna must learn to forgive Fox for his transgressions and move towards a truce with him in order to overcome the evil in which she, her sister Ytena, and her brother Raven all search. For the good of Man, she undertakes the task. There is a difference in the evil which lurks in this place, and the mischievous nature of Fox and Raven, a difference which she must learn to accommodate. Evil and the natures of Tricksters are much different, and it will take the magic of her words to convince the world of Men to realize these differences.
Yna, Ytena, Fox, Raven, and Ergo all fight against the darkness, to find its oily nature hard to capture and remove. There is only one chance to remove it, and they must all make the decision in order to succeed.
