The fact that Kirkus praised this is enough to put me off it. "Witness the army of Rome at the height of its power in this popular history that follows the military feats of the 10th Legion's tactics, battles, and daily life" but the tenth was only one of four legions Caesar had under his control. It was one he levied himself and supposedly liked, but this was the same legion that broke and fled with the other three at the Battle of Dyrrhachium. It was the thirteenth with which Caesar crossed the Rubicon, not the tenth. The book itself may possibly be a decent history and a worthy read for interested parties, but the book description isn't exactly crystal clear. No suprises there.
