Hidden by Jade - Razor's Edge Chronicles, #5

I've never been one to stand idly by when a friend's in trouble. Yes, I know that to go looking into why Ilmu is missing is dangerous. Yue's still out there, and more to the point she's not happy with how little progress I've made on our deal regarding Sarroch. Which means a significant decrease in the value of my life. Staying home is therefore the smart thing to do. But all the same, a friend in trouble is a friend in trouble, and no one but me seems to care what's going on with Ilmu.
With my limited magic there's only so much I can do, but I manage to get my hands on magical incense that will allow me to see her. That is until another supernatural creature appears in the smoke and drags me into whatever space Ilmu is trapped in. And just like that, my problems with Yue look pretty insignificant. Perspective, huh? Please note that this is book 5 in a continuous series, and the author recommends that you start with book 1, Touched by Magic.
