Bride of Ash & Dust by Meredith Hart

Marry the king’s assassin. Uncover his secrets. Do not fall in love.
Princess Lilias has one day to pack her life into trunks before her wedding to a man she’s never met. They call him the Snake of Vsenrog: assassin, spy, and the foster son of a ruthless king. Everyone tells her to be terrified.

They’re right. But not for the reasons they think.
Because Zarek isn’t cruel. He’s careful. He sleeps with daggers strapped to his body but refuses to touch her when she’s drunk. He climbs through windows but asks permission before his fingers brush her thigh. He walks through palaces and slums like he owns them, but avoids their bedchamber. Keeping her safe, he claims, means keeping his distance.

And Lilias learns that the worst torture isn’t fear. It’s wanting.
But when their honeymoon tour becomes a trap, staying apart is no longer an option. As Vsenrog’s armies gather, Lilias and Zarek realize their forced marriage might be the opening move in a war neither of them saw coming. And in a palace where mirrors are windows and lovers are spies, falling in love isn’t romantic.

It’s a weapon.

And someone’s waiting to use it against them.
