Nyn lives in Twentieth century Ireland where the people no longer do the old ways of the Sidhe. She was fae born and left in the mortal world where only few races lived. Among those races were humans, fairy's, goblins, and other creatures. Nyn can seem to figure out what type of fae she is. She looks like a normal human being. Until you get to the pointed ears, blue hair, and the large feathered wings. Wanting to know what she is, she enlists the help of Ava, a forest Sprit, and Epona, the Goddess of horses and hunt; in order to use the power of Sidhe to cross over to the fae world and find out who she truly is. But when she finds out, will she be able to accept that the annihilation of the human race rests on her shoulders.
