For the life of me I've been trying to remember the name of an SFF book I read about 15 years ago. I think it was called Kirin or something like that (but the name doesn't come up in a search). It was about a woman that is out running and gets transported through a tornado like vortex to a different world where she initial is a slave/servant, but eventually achieves freedom. There is some underlying story about her ability to help infertile women in the world. She later finds out that she was wrongly taken from her own world (where her husband and children live) and cannot go back because it is now thousands of years in the future on earth.

Does anyone remember the name of this book?
