Over three thousand years ago, the legendary Celtic champion Cuchulainn was killed by order of the evil Queen Meadhbh. His wife, who had just given birth to twin boys, died of grief and a broken heart. To protect the orphaned twins from the wrath of the queen, one child, Ferdia, was sent to live with his grandfather in Tir na nOg, the land of eternal youth. Fergus, the second boy could not make the journey, and so the twins were separated. Ultimately the two boys grow up in the same land...but in very different times. While the first book in the Legends series is the story of Ferdia as he begins life in 21st century Ireland, this second book follows the life of Fergus who remains behind in Celtic Ireland. Fergus becomes a great champion like his father, "reddening he blade with the blood of Ulster's enemies, but all the time he longs to be with the twin brother he never knew."
