Fire Study by Maria V. Snyder

This is the third book in the fantasy series featuring Yelena, who at the beginning of book one was given a choice between execution and become the Commander's food taster.

It's now a while later, and Yelena is coming to grips with her new family from a different land, her abilities as a magician, and the revelation that she is a Soulfinder.

It's been ages since I read Poison Study and Magic Study, so it took me a while to get back up to speed on all the politics and arguments going on in this novel. I still enjoyed the characters (Valek!) and the action, but it took me a while to get reacclimated.

I'm not sure if Yelena's story is done, though!
