I'm not going to write an elaborate review on this because I think it is safe to say that my opinion on these books is biased. I love this series and I basically grew up with them during High School. This last book in the series is somewhat different than the previous ones, as it checks in with our friends from the Upper East Side every New Year's Eve for three (or four?) years straight. I loved finding out how Serena, Blair, Nate, Dan, Chuck and Vanessa were doing and the ending was satisfying.
