A Kiss of Iron (Shadows of the Tenebris Court #1) by Clare Sager

In the cut-throat game of court life, masters manipulate pawns-and you never know which one you are. One thing is certain: there's no space on the board for love.

A penniless noblewoman, Kat is on the verge of losing everything when she's offered a well-paid job that could be her salvation... or her ruin. Drawn into court's deadly intrigues, she's given a single task: spy on the powerful fae lord known as the Night Queen's Shadow.

Bastian Marwood is handsome, ruthless, and cunning, but Kat can't decide if he's a threat to her kingdom or just her heart. To uncover the truth, she must play a dangerous game of desire and deceit, pushing him to reveal his secrets while protecting her own. But Bastian's shadows have a hold on her-one she isn't sure she wants to escape.

Kat soon learns that at court, nothing is as it seems and even the best-laid plans can be destroyed in an instant. As a pawn on the board, she can't afford to fall victim to love-only fight for survival.

A Kiss of Iron is the first book in a new series featuring court intrigue, a morally grey hero, and an unforgettable enemies-to-lovers romance. Perfect for fans of Gild and From Blood and Ash.
