I rather randomly picked up the first four books in this series a couple decades ago when I was in France. It was a rather new experience for me as a Canadian to read a graphic novel with adult content. It is funny! I also learned a lot of vernacular and adult French in the process. Plus, I really liked the vibrant art.
The Trolls are awesome.
So this is part of the “Lanfeust” universe, right?
There’s also a mega-series in which each sub-series is named “Elves,” “Orcs,” “Dwarves,” etc, but I think this isn’t part of that.
