After a deadly plague suddenly reappears after one hundred years of dormancy, Aaryn, a curious and kind fairy who spends too much time exploring alone, finds himself attacked by the Royal Guard of the Human realm. But before they can lay a hand on him, Aaryn is protected by a woman wielding an extraordinarily powerful weapon. He's not sure why, but Ria seems devoted to keeping him safe. And he can't seem to shake the feeling, there's something he's missing . . . On learning about the new outbreak, Aaryn agrees to visit the Human realm to speak to King Isak, in the hopes of helping the king find a cure to the second One Hundred Year Blight before it consumes his people.
