See your future in Facebook?

I was immediately hooked on the main idea in The Future of Us by Jay Asher and Carolyn Mackler.  The time is 1996, when many families were buying their first home computer and receiving American Online (AOL) CD-ROMs in the mail for free time on the Internet.  After Emma logs on to AOL, something strange pops up - "Facebook."  Of course, Facebook hadn't been invented yet, and when Emma sees a picture of herself, obviously much older and with a different last name, she figures out she's looking at her future in 15 years and it's not a happy life.  Her friend Josh finds his future Facebook page, too, and he's ecstatic to learn that he's wealthy and married to the hottest girl at their high school.  Every time they check Facebook, something is a little different; Emma and Josh learn that changes they make now, even small ones, impact their future.  The reader will easily figure out the direction of the book (are Emma and Josh just friends...or more?), but watching the ripple effect of their actions is pretty cool.  A great book for high school kids and older, more mature middle schoolers.
