It was a pretty easy book to listen to. At first the AI got a little annoying as he described the items and achievements, but after realizing it was the aliens way of acclimatizing to human entertainment, it got easier to understand and tolerate. Though more often than not it got a good actual chuckle out of me so it was fun to listen to. *on a side note: the way Jeff Hays talks reminds me of comedian Ben Bailey so it started it off on a good, comical foot for me.
