Vision in White question

I read this book years ago and for the life of me I can't remember the title or author! I do know some things about the book though! The heroine was somehow forced into an abusive marriage. The husband would sexually abuse her and had a maze with a lewd statue of him in the middle. After she escaped she met the hero and he eventually coaxed her to love again. The hero eventually killed the ex husband in the maze. Someone please please please remember the title! Thanks!

Also sorry for the spoilers!
