It was a type of fantasy book set in a cold snow covered world. The people who lived there used "fire rocks", rocks they burned to stay warm. These rocks had to be found by seers of sorts, always men. Only a few people had this power to find the fire rocks so they have formed a type of council, and are very important to their communities. The main character is the first woman to be able to find fire rocks as well. Because she is a woman, the men do not want to believe she has this power and try to kill her. She escapes to a town no one knows about and falls in love but realizes she is avoiding her destiny. So she goes and confronts the council, who give her a test that she passes. I checked this book out of a library, and it was in the adult fiction section towards the front. So I would assume the author to have a last name ranging A-D or so. If anyone can help me I would really appreciate it!
