The Long Earth was fascinating and thought provoking. I have to say I tried again and again to engage my husband in conversation about "what if" and all the thoughts that this story brought to mind. 
 I do lament that there wasn't as much of Terry Pratchett's signature humor as I was anticipating. I could definitely see some of it here and there but I surely wanted more. A downside is it took me quite awhile to finish this one. I thought I would gobble it down in a day but for some reason I just couldn't get sucked in, even though I did really enjoy it, there was just so much awesome description and things to read about, all the POSSIBILITIES I SAY!!! haha. 
 I really think part of what gave me trouble was that I couldn't pin down until about 100 pages the main characters in the book were. Also, this was a very slow moving read, there wasn't enough action compelling you forward. It was a book for contemplating. There was so much rich explanation and jumping forward and backward in time that I didn't feel the urgency to finish it quickly that I do with some books. I didn't see a main story arc progressing. Even by the end of the book I thought - now what was REALLY the plot? 
 Because it moves a lot from character to character, stringing a bunch of things and events together I was often wondering "why the heck did they choose to include this person's story" only to understand their madness later on during the book. It did give me a bit of a disjointed feeling. 
 The Long Earth had a lot of interesting scenarios and things that made you think, "is that how humanity would really react?" moments - but ultimately I felt like it was incomplete. The book ended way too abruptly. Yes, the main character Joshua figured out a few major things with his traveling companions, and there was character growth on his part that I was happy with but most of the last events in the book seemed so anticlimactic. Once I did reach the end of the book my reaction was "Is that IT???" It just didn't feel like its own complete story...even if a book is meant to be a series I still think the individual book should be able to stand on its own. Obviously, I think there is going to be another book, and while I enjoyed this one I'm not foaming at the mouth for the next one if it goes in a similar fashion as this one. I'll of course read it though *evil laughter*
