The Kephrath series
The Kephrath series of books is set in the ancient near east, towards the end of what we now call the Late Bronze Age. Long-standing nations, empires, and ways of life are beginning to break down, and nobody yet knows what will replace them. Groups of people, displaced from their former homes, are seeking to settle elsewhere, and conflicts arise with the current inhabitants.
The series opens with In a Milk and Honeyed Land, following a young village priest as he tries to reconcile his calling with the injustice of his plight at the hands of the local chieftain, and the unknown threat of new, warlike, would-be settlers arriving in the hill-country where he lives.
