I am looking for the title of a book and the author. It is a older historical romance about an Amish girl who was sent to an asylum to work for her uncle. The Amish girl was taking care of a man who had a stroke. The man escapes from the asylum with the Amish girl as a hostage and they are running from the law. If anyone can help with this I would really appreciate it.
Thanks!

Is it one of these book sir?

Blue Asylum by Kathy Hepinstall

Or

The Book of Madness and Cures by Regina O'Melveny
