First of all, if you haven't yet - go read Jay Asher's "Thirteen Reasons Why" instead. It's SO much better! That said, I was actually very pleasantly surprised by this book. I'd heard such mixed reviews, that I didn't know what to expect and thus ended up enjoying quite a lot more than I had feared. I found the premise fascinating and was interested in seeing how Jay Asher and Carolyn Mackler handled it.In parts, this is a typical YA novel, but the sci-fi aspects makes it refreshingly original and different. Some issues I think were skirted somewhat and/or handled too superficially, but all in all, I liked the direction the novel took, and felt it ended the only appropriate way.It's a fun read, even if it did come across as a bit of a let-down after reading Jay Asher's first book, "Thirteen Reasons Why", which absolutely blew me away. Thankfully, the books are different enough that I wasn't really tempted to constantly compare.
