I listened to the audiobook version of this book before taking a look at the hardcopy. The narrator of the audiobook version did a great job of changing voices between Elliot and his companion. The way the narrator breaks to explain the illustrations and how she explains them is well-done, as well. For those who enjoy the Mr. Robot television series, it might be a novelty to see a hardcopy of Elliot's journal from Season 2. Otherwise it doesn't add any insight into Elliot, any of the other characters, or the plot.
