Our heroine, Mirian, is mage who flunked her university courses and has no "mage marks" in here eyes, even though she tested high for mage power. Tomas is the younger brother of the Pack Leader, and the last survivor of the battle to hold their border against the Emperor. They find themselves thrown together when each of them sets off to save the captured mages and they themselves are captured by a very determined army captain, Captain Reiter.
The beginning of this was a little slow but it picked up and never stopped after about the first quarter of the book. Lots of action, not too much political intrigue, and a villain you have no problem hating made this a thoroughly enjoyable read.
