Book 1 of Song Of Albion. Lewis is drawn from the dreaming spires of Oxford to the misty moors and glens of Scotland, expecting nothing more than a pleasant weekend away. But the road north leads him through a mystical crossroads, and he finds himself in a place where two worlds meet in the time-between-worlds. The ancient Celts admitted no separation between this world and the Otherworld; the two were delicately interwove, each dependent on the other.  This balance is now disturbed – a breach has opened between the worlds and cosmic catastrophe threatens.
