I typically end up doing a 70/30 split of listening/reading when I go through my books but there are times when that flips due to the quality of the voice actor/narrator. I have nothing against David Stifel but I find his performance to be incongruent with the story being told, not to mention the lack of range. As a consequence I listen to the book as a last resort and stick to reading, which makes my progress through the books sometimes painfully slow.
I think this will be the last of the series I pick up.
