Kingdom of Chains by Tanya Bird

She was trained to please. He was trained to kill.

Isabel Maddock is living a lie. She is betrothed to a man she loathes, living in a place she does not belong. But the home she craves no longer exists, and the people from her youth are gone. Or are they? The wastelands are calling, but they are not for the faint of heart. Luckily a certain defender is close by to keep her safe. Very close. Too close. Into the wastelands they go, equally unprepared for what they will discover…
Ryder Blackmane is a defender for life. His comrades are his family, and keeping them safe is all he has to offer the world. So when they are sent over the wall to investigate happenings in the east, he goes willingly, immune to everything outside of his orders. That is until he meets Lady Isabel. She is a caged bird whose scars call to his. Best to ignore the calls and follow orders. Follow orders. Follow orders. Loyalty is everything, but the lines are blurring…

Kingdom of Chains is a standalone medieval dystopian romance. If you like a dark setting, heart-pounding action, and witty dialogue, then this epic love story is for you.
Trigger warning: Domestic violence (not between hero and heroine).
