The main idea

A girl reluctantly goes to England on her mother's orders. Her mother, being Brittish herself, wanted the girl to have an idea of who her anncestors were.

Girl visits a castle on tour, and slowly begins to take interest. Down in the dungion, she imagines herself actually a prisoner there within it's walls. Taken by fained dispair, she goes to the window to "plan" her escape.

Long story short: She acidently goes back in time. Meets up with people who are speaking a different English than what she knows, and have a whole different way of looking at life.

It's a major culture shock for her, but not so bad as that of her new neighbors. Her strange talk, dress, the fact that she's not from any known country, even the things found in her odd bag, all seem to identify her as a witch.

What is going on here? And what does her mother have to do with it all? Can the girl find out and escape before she is burned at the stake??
