A woman, Pip, apprentices at a magic hotel to train as a detective. Also, there's a big event coming up and a magical thief stealing property from guests.
To be honest, they could have ditched the entire detective/thief plotline and just used the bellhop at a magic hotel setting and I think I would have been more interested. There's also half-magical people in the setting that felt like a really obvious racism metaphor that never really developed i.e. the lead is half-magical, meaning she can't use spells (though may be able to with more risks involved) and full-magical couples can give birth to full-magical children, but once you have a non-magical or half-magical person in the genealogy, you can only be half-magical at most. There's also some weird co-dependent sibling drama.
The lead has a girlfriend that didn't add much to the story other than some relationship drama and I guess to tell the audience that she's a lesbian so the author can have a romance plotline with the bartender if the series continues? It's pretty minor, but I still can't put it on my "no romance and lgbt major characters" shelf as there's a side story with a depressed widower pining for his dead wife.
