A Veil of Stardust and Savagery by Analeigh Ford

There’s a reason the Starlight Fae are known as the greatest tricksters of all.
Unfortunately for Delphine, she’s just begun to learn that for herself.
She was warned they were not to be trusted—even when those same fae claim to share the blood running through her own veins. True to his word, Seren did not let Delphine die in Avarath, but he didn’t take her home, either.
No, the king of the Starlight Court took her even further away. He took her to another faerie realm.
He took her to Elysia, a place so far from the human realm that stories of it never so much as made it to their legends.
Unlike Avarath, this realm’s glamour is still intact, untouched by the ravages of time. Elysia is everything that Delphine expected faerie to be. It’s everything that Avarath wasn’t.
It’s ethereal. Enchanting. Inviting.
But in some ways, the ways that matter the most, the two realms remain the same.
Elysia is still faerie, and so despite Seren’s promises to protect her, it’s the most dangerous place for Delph to be… especially when the four fae who tried to kill her once somehow do the impossible and find her again.
Caldamir. Tethys. Armene. Nyx.
The four princes of Avarath.
The four princes who betrayed her.
The re-emergence of the Starlight Court has changed everything, but not in the way Delph might have hoped. Certainly not in the way that would allow her to forgive the princes for what they tried to do—what they’ll inevitably try again. The collision of realms broke something, and it’s only a matter of time before even Delphine’s own fae turn on her too. She can feel it.
If she’s going to survive in the realms of faerie, she’s going to have to learn how to play the game. Or, more specifically, the art of the deal.
She’s already made one deal with the king of this new realm and lived to tell the tale. This time, she’ll make sure she gets what she wants out of it. This time, she’ll make sure she gets home.
Truly home.
To Alderia.
If the other fae don’t beat her there first.
