Ebony and Ivory

Huw wakes up from blackness, his head hurting. Why is he bound hand and foot, in the back of a large truck, hurtling through a sandstorm? Huw's nightmare is just beginning. He finds himself a prisoner in the dungeon of an ancient castle, in a strange, strange world. As he slowly regains his memory, feverish images of the past return in flashbacks. What do the strange dreams about black and white horses mean? And who are the women riding them?
