Origin of Druid (Druid's Path Book 1)

A druid is given a mysterious white stone. Kermode, the druid, learns the stone holds supernatural powers. Kermode’s use of the white stone to benefit the tribe leads him to be named as the Elder. Kermode takes a wife. Over time, as the power of the stone dwindles, Kermode’s wife, Idellsa, bears him a son.
Elgin, a wealthy land owner, is deep in debt to the Romans. The payment demanded is Elgin’s infant son. Elgin hatches a plan to kidnap Kermode’s son Durst. Idellsa is killed. Durst is given to the Roman in place of Elgin’s son.
The lives are Kermode and Durst are played out from the wild forests of Britain to the marbled halls of Rome.
