I liked the concept of this book. The idea if seeing your future in tiny Facebook snipets is interesting. What would you do if you could do that? Would you try to change your future? That's pretty much what happens to Emma and Josh as they're able to log into FB in 1996. There is an important message: don't get too bogged down in things you can't control like your future and try to stay grounded in what you can control which is the present. The middle of the book was not as fun to read as the beginning and the end because the authors give us a lot of details about the character's lives that bored me some. Also there were times when Emma displayed a lot of entitlement and was rather mean to Josh. But I overall I liked this novel.
