This book was so much fun. I laughed out loud reading about and remembering the brave new world of computers in 1996. I'd forgotten that, back in the 90s, you couldn't be on the internet and the phone at the same time. This book is about two friends, Josh and Emma. Emma gets a new computer and an AOL CD-ROM. When she puts the disc into her computer, and logs onto Facebook, she can see her future ... and Josh's. She's not entirely happy with what she sees, so she starts to try to change the future. And of course, we all know from movies (Back to the Future, etc.) that can be a dangerous thing!Each chapter alternates POVs, from Emma's to Josh's and back again. It was hard to tell if the each of the two authors wrote a POV, as with Nick and Norah's Infinite Playlist. All in all, I found this a charming book and a really fun read.
