The Eagles' Brood (The Camulod Chronicles)

Most know the leader of the Colony as Merlyn; all call him Commander. Caius Merlyn Britannicus is responsible for their safety, and all look to him for guidance, leadership and justice. It is a harsh life, but a good community, and Merlyn is dedicated to spreading the influence of Roman culture beyond the Colony's borders. Uther Pendragon, the man who will father the legendary Arthur, is the cousin Merlyn has known and loved since their births, four hours a part on the same day. Uther is the timeless warrior, the red dragon to Merlyn's great silver bear, and between the two of them, the colony of Camulod knows few enemies. In a world torn apart by warfare and upheaval, each is the other's certainty and the guarantee of the survival of the Colony...until a vicious crime, one that strikes at the roots of Merlyn's life, drives a wedge between them and threatens the fate of a nation.
