The Silent Fort — Fay Sampson

The Roman army is invading Devon. In hill forts and sacred groves, druids and warriors quarrel over the fate of their tribe, and the chief's son, Aidan the Red Fox, takes matters into his own hands. Cairenn is on the brink of marriage to Aidan, and her brother Melwas demands the weapons of a warrior, though he is still too young. Carienn is torn between fear for her lover, her brother, and her people. As male and female druids compete for the soul of the tribe and the Roman legion marches relentlessly closer, brother and sister plunge into danger.
