The Eagle and the Wolves by Simon Scarrow

Thoroughly enjoyable Roman Empire romp following Scarrow's heroes Macro and Cato as they command centuries of local auxilliaries in the fight against Caratus during the Roman conquest of Britain. It is hard not to feel sympathy for the Celtic tribes as they face the inevitability of conquest. I am reading the Eagle series completely out of sequence but it doesn't matter because each book stands in its own right.
