Help! I am so muddled up. My daughter asked me for recommendations for fantasy series that I enjoyed. I remembered one I reads few years ago. It has a female government agent who starts developing a relationship with the leader of a group of where's in the. Mountain west. The leader has the ability to travel through shadows. There is war with vampires in one of the books. Unfortunately I cannot remember the author, the series title, or the names of the characters. NE1 have clue about the series name or author?
