The Paradise War (Song of Albion, Book 1)

Drawn from the dreaming spires of Oxford University to the misty moors and glens of Scotland, Lewis Gillies expects little more than a pleasant weekend away. But the road north leads to a mystical crossroads, and Lewis finds himself in a place where two worlds meet—in the time–between times. The ancient Celts admitted no separation between the world and the Otherworld: the two were delicately interwoven, each dependent on the other. In this first book, a breach has opened between these two worlds—and cosmic catastrophe threatens.
