Until Eternity

Emilia "Lia" Elementa runs away from her aunt's home and ends up wandering into fey territory. Meanwhile, Mabon Cadwallader is avoiding the ghosts haunting his town but ends up running from home upon learning about a recent family tragedy and his destiny to become Arawn, the Welsh god of death's apprentice. The two come to a head in the feys' nest and their fates and hearts become intertwined, especially when Mabon's brother's job at the paper mill goes haywire and creates a murderous smog.
Underlying this, Lia must come to terms with witnessing her parents' deaths, and her own powers, while Mabon is dealing with a personal tragedy.
