"Stuart Langton...is particularly adept at handling dialogue, skillfully moving between characters at a lively pace." -AudioFile

"Lawhead treats his Celtic lore with respect; the upshot is well handled and pleasingly restrained, a solid and readable opener for the series." -Kirkus Reviews

In an ancient cairn in the wilds of Scotland, Oxford student Simon Rawnson vanishes, seemingly into thin air. Where has he gone? Unsettling signs-a mysterious Green Man, a Celtic circle chalked on the sidewalk-point his roommate, Lewis Gillies, to an impossible answer-and to an incredible destiny on the other side of a doorway between worlds.

There, where Celtic champions, magic, and treachery are woven together in the beautiful and brutal land called Albion, Lewis finds Simon. And there, schooled as a warrior, he is thrust to the front of a titanic struggle between light and darkness-a hideous, onrushing darkness that would devour not merely a kingdom but two worlds.
