Dhonielle Clayton

Yes.

Jessica Townsend's Nevermoor, The Trials of Morrigan Crow, Holly Black and Cassandra Clare's The Iron Trial, and Dhonielle Clayton's The Marvellers.

Okay, I wanna look at Nevermoor first because Morrigan Crow's starting point is so incredibly bleak.

Bleak is an understatement.

It makes the protagonist an underdog even when they are technically part of the elite class of society

Exactly

And then we have the third book in this group, The Marvellers by Dhonielle Clayton, which takes all that hidden world wonder and just explodes it on the page

It's visually stunning, even just in the world-building
