Third in the "Smoke &" series by Tanya Huff...
Alrighty... since I've already talked about this series quite a bit before I'll skip rehashing all of that.
So Tony realized in the last book that it'd be a good idea to actually work on the whole wizard thing so he has a bit more control of his abilities in this one. Still not great, but better than last time! Which is good since there's all kinds of nastiness being shoved through various gates that he has to take care of.
There's also all kinds of business with Lee and the two of them finally relating to each other as people instead of PA and star.
