Outcast (Sacred Amulet, Part One)

Ugo’ji is an outcast, an untouchable. She lives on the fringe of society as the lowest of the low, a living sacrifice to the gods. The only person she interacts with is her aged grandmother Nne who nurtures her powerful gift of healing. Until the day she meets Ebube a strange warrior to their lands. He ignites a yearning within her she's unable to ignore.
Ebube is drawn to the young maiden with the emerald green eyes who possesses the body of a goddess and the healing touch of an angel. But he is forbidden from mating with a human and the consequence is the wrath of the gods.
Moreover he is on a mission. If he fails, the gates of hell will be opened and the earth plunged into darkness. He cannot stay and she cannot go with him.
