Clash Of Iron By Watson, Angus

LEADERS ARE FORGED IN THE FIRES OF WAR
Iron Age warriors Dug and Lowa captured Maidun castle and freed its slaves. But now they have conquered it, they must defend it.
A Roman invasion is coming from Gaul, but rather than uniting to protect their home, the British tribes battle each other - and see Maidun as an easy target.
Meanwhile, Lowa''s spies infiltrate Gaul, discovering the Romans have recruited bloodthirsty British druids, and Maidunite Ragnall finds his loyalties torn when he meets Rome''s charismatic general, Julius Caesar.
War is coming. Who will pay its price?
