Hunted by giant primordial beasts, red in tooth and claw, a tribe of cavegirls scratch out a bleak existence in a brutal uncaring world. They cling onto a life where not many make it beyond the first few months, let alone to adulthood. Governed by ancient laws and arcane rituals - the only constants they have - they follow the old ways on pain of death. But One Path, a hunter and warrior, has a plan to change their lives. To free them from the toll the great predators that stalk them charge, and it will overturn everything they know.
