In 60 CE, Boudica set out to defeat the Roman invaders. She did; and left behind a legacy that changed history.
Samhain eve, three hundred years after the goddess Boudica sent the Roman armies scurrying back to their own lands; in saving another, Arawn of Atrebates kills his sister. In an era dominated by women, there is no man more despised than a sister-slayer. He flees to Gaul and is initiated by the Bagaudas, a rebel group who support Rome's new one true God by killing pagans, and discovers his destiny is to lead them to Rome and bring the priests back to Brython and rid it forever of Boudica's legacy.
Sulis, Warrior-Queen of Cantiaci, a tribe hated by all others for welcoming Julius Caesar onto their lands, fights to unite the tribes to create a single peaceful nation. But she faces fierce opposition, not only from neighbouring tribes, but from among her own people.
Heddgwyn, Arch Druid of Cantiaci, intends to claim the lands for the Druids and reclaim them for the old gods, and for men.
In the shadow of the Blood Moon, the fate of all Brython will be decided.
