Starfallen by Fern Cole:
 
Perfect for fans of The Hunger Games, ACOTAR, and Fourth Wing!

A 23-year-old morally grey, grief-fuelled, self-destructive, sarcastic little menace enters deadly fae trials, hoping to bring back her dead boyfriend.

Officially, Cassandra competes for a wish. Secretly, she has another agenda.

But the Court is more than a stage for bloodsport. Contestants are permitted to live, work, and roam among the Fallen Fae between trials. Seeking distraction, Cass accepts a post as assistant to Kieran, the King of the Fallen.

She wants to use him for the trials,
and he finds her defiance amusing.

It doesn’t take long for this mutual manipulationto turn into equal obsession.
