Leda, a young woman who moved to Japan to escape her abusive family, is slowly adjusting to her new life. She's learning Japanese, making friends, and enjoying the summer festivals. On the day of the famous Tanabata festival, she finds a small shrine - but when she steps out of the shrine, she steps into Edo Era Japan.

Trapped 400 years in Japan's past, what follows is half fantasy, half historical fiction. Is her coming here an accident? Or does it have something to do with the sudden appearance of European ships off the coast? Leda must discover how she ended up in this situation, and how she can get back home - or if she even wants to go back.
