Amber & Dusk by Lyra Selene; 2018. Hardcover. (YA)

In a magical world where the sun never sets, a gifted girl dreams to be in the royal court but once inside, she may not be prepared for the drama.

Sylvie has always known she deserves more. Out in the permanent twilight of the Dusklands, her guardians called her power to create illusions a curse. But Sylvie knows it gives her a place in Coeur d'Or, the palais of the Amber Empress and her highborn legacies. So Sylvie sets off toward the Amber City, a glittering jewel under a sun that never sets, to take what is hers.

But her hope for a better life is quickly dimmed. The empress invites her in only as part of a wicked wager among her powerful courtiers. Sylvie must assume a new name, Mirage, and begin to navigate secretive social circles and deadly games of intrigue in order to claim her spot. Soon it becomes apparent that nothing is as it appears and no one, including her cruel yet captivating sponsor, Sunder, will answer her questions. As Mirage strives to seize what should be her rightful place, she'll have to consider whether it is worth the price she must pay . . .
