Black Prism was good. I really didn't like the audio book though; it was Graphic Audio, and they put music and sound effects in it, and have a different voice actor for every character. I didn't think I would mind, but at times the sound mixing got out of whack and the sound or explosions or whatnot got way too loud and I couldn't hear the narrator. That was pretty annoying. The magic system is interesting and unique, and either I am getting more clever or writers are getting less crafty but I saw the big "twist" of the book way before it actually happened.
