Gate of Ivory, Gate of Horn

Several years ago, Christian Huxley's father, George, obsessively documented the strange phenomena emanating from Ryhope Wood at the edge of their property. He watched the ancient heroes emerge, shouting both incomprehensible warnings and unmistakable invitations. Recklessly, George followed them inot the mysterious sylvan shadows that changed him forever.
Christian himself was not untouched by these living dreams. A childhood encounter with a phantom from another time draws him to the Wood as an adult. Deep in Ryhope, Christian uncovers the lie that permeates his worst nightmares. And like his father, he will be consumed with the mythagoes of Ryhope, especially a young Celtic warrior called Guiwenneth. She is the key to the mystery of the universe, an ancient heroine caught in a timeless tale of bravery and sacrifice.
Now, together with a band of crusaders from a world long gone, Christian and Guiwenneth become part of the unfolding stories both remembered and forgotten. They meet sorcerers in battle and giants who can travel miles in one step. And they discover the meaning of the two gates, Ivory and Horn - one the lie, the other the truth.
