Auracle has one of the funnest, most distinct heroines I've read in a long time. How she feels/thinks/interacts feels so genuine that it is almost like she can step out of the pages, shake off the print, and go about her real life in front of me. I really liked astral projection. It was a "magic system" I'd never seen before and it was handled in a thoughtful yet intriguing way. The side characters, Rei, her mom, and her alcoholic dad, were fleshed out in their own ways.
That being said, the plot had some serious issues. For a book that's less then three hundred pages having a whole hundred page gap in any really development for a hundred of those pages was a problem. I hope her next book deals with that.
