I got this audiobook because it was part of the Neil Gaiman Presents line of audiobooks on Audible. And, being the Gaiman fan that I am, I've listened to a number of the books from that group and they've all been... interesting. This is by no means my favorite book from that set, but it was very interesting.
As happens with older books, it was a little dry for my taste. I'm also far from certain that I got all of the humor of the book, but some of it was obvious and carried even to modern times. I got a number of laughs out of his ribbing of the US.

In short, I liked it alright but I didn't love it and I'd recommend it only with caveats. But I'd still recommend it to the right people.
