I have to say, these Doctor Who audiobooks are very well done! They are entertaining, well narrated, and easily conjure pictures from the TV episodes as I listen to them, even if I've not seen the entire episode (as was the case with Doctor Who and the Visitation).
There were a couple of points in this audiobook that the sound effects occasionally overpowered the narrator's voice, but this was rare, and only happened in the very beginning of the book. Overall, this was a good one to listen to as I made my way through some monotonous work for a couple of hours!
