The Long Earth

The last third of this novel really came together for me; I don't know if it was that the pace picked up slightly or that it became a simpler narrative, but when it finished, I literally stopped cycling on the bike path (listening to the audiobook) and said “it can't stop there!”.
Style-wise it reminded me of Ringworld in that it was more about the concept of the world-building than a plot. That really bothered me in Ringworld, which I lemmed, but there was enough plot in this to keep me going. The concept of the long Earth was really cool and thought-provoking, especially the thought of how different colonies of humans will evolve differently, potentially even becoming different races with time.
