Lore of the Wicked Wood by Hillary Raymer (Whispers of the Wicked, 1 of 2)

Atlas Skye is the renowned prince of pleasure with the magical ability to elicit desire. Repulsed by his son’s shameless reputation and blemished character, the kralv issues Atlas an ultimatum. Find a wife or be shipped to a remote camp in the mountains to mine for fire rubies. Unfortunately for Atlas, there’s only one female he wants, and she hates him.

Everinne Auvyre is touched by death. She thrives on careless decisions to avoid her volatile magic and the nightmares haunting her. When her brother refuses to aid her destructive habits, she finds employment at the Mystic Obscura, an exclusive parlor full of provocative entertainment, where the price to enter is a single drop of blood.

Yet the gilded streets of Prava are no longer safe. Immortals are being hunted and the wicked wood is awakening. When Everinne’s magic is discovered by the kralv, she’s forced into an unjust bargain-become his puppet and marry Atlas, or surrender to her greatest fears. With Everinne entrenched in the clutches of the Mystic Obscura, Atlas struggles to find a way to free her from its grip and uncover the missing immortals. But when Everinne’s only friend vanishes, the two must navigate the city’s sinister underbelly, before they lose their kingdom, and each other, forever.
