The Son of the Swordmaker is set in Roman times, during the time of Christ's crucifixion. The hero, Eradmus, becomes part of the Roman invasion of England. He is captured and falls in love with Vloden, the daughter of the tribe's "king." Upon his escape, he returns to Rome, and resumes his military career. Even after he becomes the leader of the Roman troops who arrest and subsequently crucify Jesus, he never forgets the love of his life, Vloden.
