The premise of The Future of Us is a lot of fun, intrigue if a bit whimsical. In 1996, two teenagers find themselves able to log into Facebook, something hasn't been invented yet. They get to see what their lives are going to turn out like and this sets off a chain of events they didn't even think possible. 
 I guess a big theme in the story is choice. When they find themselves of Facebook, Emma and Josh are suddenly faced with the choice of fitting their presents into the futures or just letting things be. I actually found Josh to be the more mature one of the pair. Emma seems very set on getting what SHE wants, with little to no regard for others. As she puts it, it's because she got the sucky end of the straw but Josh got lucky but the way I see it, every time she decides her future is not to her liking, she does everything she can to change it, but not by making any REAL change to her present. She comes across as very shallow because all she does when she finds out that she HAS A GLIMPSE OF THE FUTURE is worry about her future husbands. 
 At the same time, Josh is a bit of a meh character for me. When he finds out who he's going to end up with in the future, he sort of suddenly decides he likes her even though they've barely spoken. That's just a bit weird for me. 
 In the end, what I liked about the novel was the non-Facebook part. Josh and Emma just trying to figure out their friendship and where they stood after that incident in November was what that really drew me in the novel. Unfortunately, there were a lot of plot lines mentioned throughout the novel but they aren't followed through, which left me frustrated. Overall, The Future of Us was a good attempt at a wonderful idea though it just could have been better.
