The Village of Bones: Sabalah's Tale Publisher's Summary
In 4386 BC, a young priestess named Sabalah conceives a magical child with a mysterious stranger named Arash. Sabalah names the child Marrah. This child will save the Goddess-worshiping people of Europe from nomad invaders called Beastmen, but only if her mother can keep her alive long enough to grow up. Warned in a vision of the coming invasion, Sabalah flees west with Arash to save her baby daughter, only to discover that she is running into the arms of her worst enemies. In the dark forests of northern Europe, other human-like species left over from the Ice Age still exist.
