Book excerpt: The Quest series from Luath Press continues with the quest for all things Celtic, an investigation into aspects of Celtic history that have previously been neglected or lost. The authors argue strongly that the evidence they have uncovered within folklore, legends, the guilds, and the oral traditions of secret societies in Scotland, link together with striking similarities. They further suggest that these links are not coincidence but the last visible threads of belief systems that have been at the center of the Scottish psyche for centuries. The Celtic Key makes sense of the underlying beliefs that have contributed to, motivated, and shaped a nation through the ages.
