The Austen Escape, by Katherine Reay, sees an American go on an Austen-themed holiday. The synopsis says: "Falling into the past will change their futures forever.
Mary Davies finds safety in her ordered and productive life. Working as an engineer, she genuinely enjoys her job and her colleagues - particularly a certain adorable and intelligent consultant. But something is missing. When Mary's estranged childhood friend, Isabel Dwyer offers her a two-week stay in a gorgeous manor house in England, she reluctantly agrees in hopes that the holiday will shake up her quiet life in just the right ways.
But Mary gets more than she bargained for when Isabel loses her memory and fully believes she lives in Jane Austen's Bath. While Isabel rests and delights in the leisure of a Regency lady, attended by other costume-clad guests, Mary uncovers startling truths about their shared past, who Isabel was, who she seems to be, and the man who now stands between them.
Outings are undertaken, misunderstandings arise, and dancing ensues as this company of clever, well-informed people, who have a great deal of conversation, work out their lives and hearts." The Austen Escape is out in November 2017.
