This book (number 4 of 6) starts a new story arc in the series, and I liked it. It has all the elements I love about this genre: the statistics, the grinding, the artifacts, and the slow progression. It is all there. The humor is just as good; the book had me laughing out loud many times. On to the next part.
The audio performance is outstanding, I loved the added sound effect, they were not too intrusive. The sound quality of the female voices was a bit off, like they were recorded in a whole different environment.
