On the west coast of pre-Celtic Britain the Old Gods of earth and sea are stirring. Once again there are portents of  imminent  disaster. The only hope for survival lies in knowledge preserved  by survivors of an earlier cataclysm whose descendants now live  far to the east.  Nhiall, a young priest-in-training, is sent on a dangerous journey across prehistoric Europe and the middle east  in search of the wisdom  that may bind the power of  the Old Gods.
