The story's pretty basic: it's about a strong and somewhat violent princess who's living alongside some vapid, well-kept princesses so she can learn to be a "true princess".
However, I like that Ugg is attending the classes so she can keep her mother's promise to find a new way of life: learn diplomacy vs. continuing the war back home for another thousand years. (I also felt for her while the other princesses would make fun of her. When I was young, I used to be bullied myself by other girls for acting too 'butch' or 'manly'.)
Still though, Ted Naifeh's art skill is what draws me in. His line work and watercolours are so beautiful. I guess I can be kinda vain when it comes to art but I tend to like comics with well drawn people (facial expressions and body language). Kinda random but I especially love that he draws men as pretty as his women characters. (Also that Ulga is short and beefy! It's not something you see often in works created by dudes).
Somewhat related: I really hoped that the live-action Wonder Woman was stocky and beefy too. I wasn't able to see the movie because $$$ but I'm of the opinion that Gal Gadot just wasn't muscle-y enough for the role... When I look at her I don't really see a warrior goddess but a physically fit runner-athlete? However, that's an unpopular opinion for another day (or lifetime).
