Savage Isle [EPUB ebook] 

The old ways are dying, and a mighty empire is reaching out across the sea. Britannia, 42AD. The wild island at the fringe of the known world is in chaos. Cunobelin, High King of the Britons, is dead. His heirs, warrior princes Togodubnos and Caratacos, have spurned the careful alliances that kept the irresistible might of the Roman Empire from Britannia’s shores for so long. In this land of warriors, druids and kings, riven by conflict, orphan boy Cullen must fight for survival within a tribe he despises. Captured by the Catuvellauni after a brutal raid on his own Atrebates tribe, he must find his purpose swiftly if he is to avoid the murderous attentions of the chief druid. As the Britons turn inward, jostling for dominion, avaricious eyes look on from across the Narrow Sea. The mighty legions gather… This is the epic story of Britain on the cusp of the Roman conquest, of a clash of civilisations and the last cries of resistance from a doomed way of life.
