Disillusioned (Lay of Ruinous Reign #2) by Briar Somerset
 
Throned but far from safe, Lilac Trécesson must honor her deal with Kestrel, the faerie king of the Court of the Valley. When a monstrous envoy arrives instead, she’s thrust into a deadly hunt for an arcane chest carried by the Midraal Market. With the help of several unexpected allies, they embark on a journey that sinks her into even deeper entanglement with the vampire forced to make an impossible choice when their mission turns to tragedy.

As neighboring forces threaten her crown and an emperor offers marriage in exchange for protection, Lilac finds herself torn between duty, her heart’s deepest desires, and the thing she’s slowly becoming. But it is Garin, her cursed and sworn protector, whose devotion turns obsessive—and deadly. The threat of her overthrow is infuriating, yet nothing devastates him more than the thought of losing Lilac to the emperor who would inevitably fall victim to his wrath if he dared lay a finger on her.

She’s his queen.
His beloved.
His thrall.
And he would raze empires to keep her.
