The Long Earth

Story: 5 / 10
Characters: 7
Setting: 8
Prose: 6

Did not look forward to this book. Thought it would be too similar to time travel books, which don't really work at all. However, it turns out that space distinctions are quite different. While The Long Earth could certainly have introduced the concept in a different way, the setting does work quite well.
This is also the first book by two authors I've had to read. They also pulled that off quite well. The story is a bit direction-less at times, but it is really the result of the adventure plot. This also turns out to be the largest failing of the book. Definitely not continuing the series, but not warning people away from reading either.
