This is the second Asterix book after Asterix The Gaul. Getafix the druid breaks his golden sickle so Asterix and Obelix need to travel to get it from the only sickle maker Getafix considers worthy. That means a trip to faraway Lutetia. Trouble is that when they arrive the sickle maker can't be found and the only golden sickles they can buy are on the black market at over-inflated and unaffordable prices. This is all bad news because Getafix needs it urgently for the imminent annual druid conference.
The drawing style is still developing at this stage in the series, and the big village feast image at the end is not there (although the customary feast still takes place) but this is still a classic Asterix tale featuring barbarians, bandits, Romans and much more. What more do you need?
