The Son of Caelryck is the third book in the Twilight of the Gods trilogy. The story opens with Aeryck awaiting the arrival of his uncle Finn from Erie, his only living blood relative and key to his father's and mother's identity. The voyage from Erie to Britain, however, is threatened by Irish pirates, and Aeryck's fears may once again come true. The Gaulish druid Boadix and his demonic obsession to rid Britain of Christianity introduce Mórrígan, a wickedly beautiful Celtic goddess and consort of the Dagda who is determined to kill Aeryck, the son of Caelryck. By killing Aeryck, the Little Bear of Celtic prophecy, Boadix and Mórrígan hope to prevent the uniting of Pictish clans under the banner of Christ and the building of the church in Loch na Huric. Aeryck, Terryll, and Dagmere, along with the chieftain Brynwald and his allies, stand against Mórrígan, her demonic wolves, and the powerful chieftain of Old Glenlouden, Drom Bonaan-Bolg. The odds against Aeryck and his fellows are overwhelming. However, with the help of Hauwka and the white wolf and the faith and prayers of the stalwart monks of Erie, there is hope. The Son of Caelryck is a story that reveals that in all earthly conflicts, the battle is the Lord's, and the gates of hell, as relentless as it is cruel, cannot prevail against Christ building his Church. The story ends in a climactic battle between the forces of righteousness and evil with a satisfying resolution in the lives of the most unlikely characters, demonstrating the power of God's infinite love and grace in the face of Christ.
