Query: The Ancient Celts

One of the worst books I have ever read. I could not get past the second chapter because it dawned on me that all he had to offer was sweeping generalities that talked around, not about, the topic. He calls Minoan culture the center of civilization (Egypt?) and in the same sentence elicits Mycenae as the topic of Homer. All this misdirection has to do with the Celts. The book is devoid of examples or any kind of grounding in specifics. The total is that it is poundingly dull.
