The Long War (The Long Earth Book 2)

I think I liked the first book in this series, but this one seemed very dull to me, basically just a travelogue of oddities in far lands. It has none of the humor of Pratchett's usual writing and is full of worry about the future of the human race. I did want to live on the back of the sentient island, but that was about the only thing I had an emotional connection to in this story.
