The Lost Sisterhood takes on historical myth - the warrior women called the Amazons - and shows us they were not mythical, but a real band of beleaguered but brave priestesses-in-training who banded together to rescue their kidnapped companions. While their desperate trek unfolds in the past, we follow Diana, a modern-day scholar who has always been fascinated by the Amazons, as she embarks on a trek of her own. Led by enigmatic Middle Easterner Nick Barran, Diana searches for traces of a fabled Amazonian treasure in the wastelands of the Sahara.
