Paranormal Romance & Urban Fantasy discussion

In the last year or so, I borrowed a book from the library. I really enjoyed it, but for the life of me, I can't remember the title or author. (And my library doesn't save my borrowing history.) I'm hoping someone on here can help me remember, because I'd like to read other books by this author.

The book was fairly recent & hard cover - I found it browsing the recent arrivals shelf, so I'm guessing it was published after 2006.

It was fantasy, and involved a woman who was part of magical military unit. They would enter a sort of otherworld with other magic-capable fighters at a central place, not actually physically fighting, although there were dangers in getting untethered from reality while fighting. Suddenly "peace" is declared, the magical militia is disbanded, but it's all really a trick by the other side.
The bad guy was a new "peaceful" foreigner who at first appeared to be romancing the woman, but their lovemaking is violent, and the woman can't escape the feeling she is being watched by dozens of people whenever they are intimate.

Does this ring a bell for anyone?

Doesn't sound familiar to me, but it does sound really interesting! I think I'd like to know also :P

Found it! Sitting here thinking about it made me remember a couple more details, and I was able to pull it up:
Talyn by Holly Lisle

I'll have to go pick it up again...

Wow! Thanks, Kate! I'm glad that one's on my TBR! Sounds really interesting! Thanks for bringing it to my attention. :)
