Looking for Answers about Bethany House The Thorn, Rose Trilogy Series #1?

Rose Kauffman, a spirited young woman, has a close friendship with the bishop's foster son. Nick dresses Plain and works hard but stirs up plenty of trouble too. Rose's sister cautions her against becoming too involved, but Rose is being courted by a good, Amish fellow, so dismisses the warnings. Meanwhile, Rose keeps house for an English widower but is startled when he forbids her to ever go upstairs. What is the man hiding? Rose's older sister, Hen, knows more than she should about falling for the wrong man. Unable to abandon her Amish ways, Hen is soon separated from her very modern husband. Mattie, their young daughter, must visit her father regularly, but Hen demands she wear Amish attire--and speak Pennsylvania Dutch, despite her husband's wishes. Will Hen be able to reestablish her place among the People she abandoned? And will she be able to convince Rose to steer clear of rogue neighbor Nick?
