Quick impressions: Another nice entry in this series. This time, when Druid Getafix runs low on rock oil, an essential ingredient to make that potion that gives Gauls superhuman strength, it falls to our heroes to go to the Middle East to find some. Light humor, a nice history lesson here or there (authors now and then do put in a footnote to real history in the text), and a few cute pop culture references. One of my favorite series.
