Treasures, Demons, and Other Black Magic, Dowser #3 - Dowser, #3

I hadn't set foot in the human world for more than a few hours in over three and a half months. Sure, I was stronger and faster than I'd ever been before, and I had a shiny new sword, but I was seriously chocolate deprived. I don't recommend quitting cold turkey. And the new sword was a problem - to my mind, anyway. It represented all the expectations of a powerful father and a new otherworldly life.
A life that wasn't the one I'd worked so hard to build. It also represented the responsibility I had to bring my foster sister Sienna to . what? Justice? I didn't know if that was even possible. What I did know was that Sienna wouldn't stop, and that I couldn't just leave everything up to fate and destiny . or maybe I was. Maybe I was doing exactly what I was supposed to be doing. If you believed in that sort of thing.
I just hoped that before the chaos and mayhem renewed, I'd manage to get my hands on some chocolate. It didn't even have to be single-origin Madagascar. I was utterly prepared to lower my standards. Treasures, Demons, and Other Black Magic is the third book in the Dowser series, which is set in the same universe as the Oracle, Reconstructionist, Amplifier, Archivist, and Misfits of the Adept Universe series.
While it is not necessary to read all the series, in order to avoid spoilers the ideal reading order of the Adept Universe begins with Cupcakes, Trinkets, and Other Deadly Magic (Dowser 1).
