[Gideon the Ninth] Does it get better?

I'm reading Gideon the Ninth by Tamsyn Muir but I've been kind of struggling lately.

I think the writing style is breaking my immersion, all the cursing in the protagonist POV seems unnatural and gives the book an overall juvenile feel to it.

I'm around page 200 and in the last few chapters nothing much has been happening, which I would be fine with if some nice character moments or worldbuilding came out of it. But no, it's just her wandering around in this decrepit palace, interacting with nothing and nobody and being bored.

I don't like DNFing books but I am lacking a reason to keep reading this one. Does it get better? What should be this book's strong suit in your opinion? Character work, worldbuilding, plot?
