When the magic tree house whisks them back to the early 100s AD, Jack and Annie find themselves in a Roman camp. The Roman soldiers are much scarier in person--and suspicious of strangers. Then a mysterious man riding a black horse gives Jack and Annie some advice to help them on their mission. But the man may not be who he seems. Will Jack and Annie be good warriors? Can they learn what makes the Roman soldiers so great? And who is the mysterious rider?
