I had high hopes for this book because I thought there was going to be this big reveal at the end as to way Josh and Emma received this AOL CD-Rom that gave them access to Facebook but there was nothing. Did it keep me reading to try and figure things out, yes! The idea of the book is original and it was fun but I felt like it was drawn out a little too much/too long. 
 For the first couple of chapters, all of the 90s references were kind of too much. Ya, I get that this was set in 1996 but I felt like I was getting beaten over the head with everything. It was fun to remember things that I use to have growing up but man, a couple of things would have been just fine. I think a student of "today" wouldn't get a lot of things but it might encourage them to research and figure out what things they were talking about. 
 I liked Josh and Emma. I thought they were strong characters and I think students could relate to them even thought it took place 16 years ago where some of them were not even born yet. Also liked the "hip" school librarian :-) 
 I'm curious to read how Jay Asher and Carolyn Mackler wrote this book. 
 Would I recommend this to a student, yes because it is a fast read especially with some of the shorter chapters (great for reluctant readers).
