Roan: The Tales of Conor Archer
The 'dark ones' are children born with strange powers only to lose their gifts in adolescence. Conor Archer comes to town, dying from a fever which makes him into something more than human. The Roan, Celtic shapeshifters inhabiting the burial Mound down by the River, try to claim him. Myth and science go to war as Conor finds his little town the center of a battle for humanity's soul.
