Skythulf is a tough and endearing protagonist. He's that perfect mix of physically confident but emotionally vulnerable which makes the scenes with Brennus, his best friend and liege, really shine. 

The worldbuilding is sketched well, giving just enough detail to feel lush in the small space of a novella. The accompanying illustrations perfectly fit the mood of the text. The sections in the forest during the Wild Hunt are particularly good, as are the flashbacks. Specifically, I love the way that the flashbacks are placed throughout, positioned to so they answer, implicitly or explicitly the trajectory of some emotion which has been expressed in the present. 

The Wild Hunt itself is great, it would be my favorite thing were it not eclipsed by the bond between Skythulf and Brennus. I love the ending, it looks like this is intended to be a series and I hope that happens.
