I read a book several years ago. I don't remember the author or title and it is driving me crazy!
I think the lady's name might have been Briana? Her father marries her to a knight. She spent their wedding night with him for a night of passion. But the next morning she sneaks out and goes back to her home. I think her father made her marry him for revenge but not sure. Anyway she goes back to her home. Her father and brother are killed and she is left to defend her home. She has a baby. Her husband tracks her down and seiges the keep. She tries to sneak out the keep with the baby but he notices her. and then he is angry that she had his baby and didn't tell him. He decides to hurt her by locking her in the tower and only letting her see the baby to feed. Since a little girl she would dive out the tower window into the sea. He was stading in the doorway when she dove out the window into the sea. He thought she was trying to kill herself but it was a way for her to escape. She came back to the caste and he was so relieved that she was ok. They have sex and then he has to leave for battle. She is pregnant again. their romance is stormy but I remeber it afte all these years. Also, when the book starts she is tied to a post and about to be set on fire (don't remember why). Before the flames reach her, her husband is there to save her. He knew she was in danger because he he had left a spy at the castle to watch over her. I think the spy was a monk.
Wahoo!!! I finally found it after weeks of searching. and it was driving me crazy! I thought the heroine's name was Brianna but that was the name of her baby. The couple was Allora & Bret. One of the best historical romance novels ever. It is "Knight of Fire" by Shannon Drake.
