It's an interesting premise, a book set around a young woman choosing whether to stay or to go. I'm just not sure all of the melodrama works for me. I also didn't really buy the rules of Mia's world, so to speak. I don't buy that someone can know things that are happening in places where their body isn't (I mean, without Skype or Facetime or Twitter or telephones). And in what time period is this book set? It was published in 2009, but it reads like it's set in the 1990s. The late 90s, though, because people have cell phones, but people don't seem to use the internet in this world. I just found the book alternately sappy and confusing. Maybe I would appreciate it if I were a teenager and not a middle-aged mom. At least I can take the movie version out of my Netflix queue now (correction: looks like it's not available to stream on Netflix anymore. Saves me the trouble).
