Twisted Desire by Jessi Elliott

Being left to lead the fae alongside an annoyingly charming partner really screws with your life.
Skylar Chen just received the promotion of an eternity. After Tristan and Aurora trade their esteemed status for mundane life, it’s now her responsibility to lead the fae.
The catch? She has to work with Nikolai Sterling. With his constant smirks and dangerous good looks, he has a way of getting under Skylar’s skin like no one else. Even still, she’d much rather be getting under him.
Sexual tension aside, they have a bigger issue to deal with. The Experiment, a human organization built on hatred toward the fae, threatens to wipe them from existence. It’s time for Skylar and Nikolai to recruit allies, bring the fae together, and prepare for battle.
Fighting to protect her people is something Skylar can manage. It’s the skeletons in her designer closet that make opening up to Nikolai where she’s suddenly out of her element.
