In the book, the heroine who is the leader of her people kidnaps the hero who is the twin brother of the king of a rival Kingdom because she thought they were responsible for the death of her husband.

Read the book about 6-7 years ago.

Bound To Please by Hope Tarr matches your description, except the hero is not a prince but the twin brother of a rival clan's laird.

If that's not the one, what's the time period and country?

That's the book. Thank you so much. You made my day.
