Nothing Can Keep Us Together is the eighth novel in the Gossip Girl series by Cecily von Ziegesar. It is the last book in the Gossip Girl series, besides the prequel, to be written by von Ziegesar herself before she handed the book series down to a ghost-writer.
It is set during the week in which graduation takes place for Blair Waldorf, Serena van der Woodsen, Kati Farkas, Isabel Coates, Vanessa Abrams (from their school Constance Billard) Dan Humphrey, Chuck Bass (from Riverside Prep) and Nate Archibald (from St. Judes). The only other main character not graduating is Jenny Hu

mphrey, who is searching for a boarding school which she hopes to attend the following year.

Plot summary

The character of Lord Marcus Beaton-Rhodes is introduced in Nothing Can Keep Us Together. He becomes the new boyfriend of Blair and is often described as a “hotter, taller, more refined, better-bred, British version of Nate…”. Lord Marcus is a Yale graduate and comes from a wealthy background. He even refers to designer Oscar de la Renta as “Uncle Oscar”. Indie filmmaker, Ken Mogul is back as he is directing a modernized version of Breakfast At Tiffanys entitled Breakfast At Fred’s set at the restaurant in Barneys of the same name. Both Blair and Serena audition, but Serena gets the part. When Blair discovers she reflects “Serena may well have gotten the part, but Blair lived it, every day." Even though throughout the book there is tension between Blair and Serena (on account of Serena being Nate’s new girlfriend and snagging the role in Breakfast At Fred’s) the book ends with the two of them kissing on the lips, murmuring “You know you love me” at Blair’s graduation party held at the Yale Club. This leads us to think that Blair and Serena are both “Gossip Girl”. But there is also an occasion to suspect Blair of being Gossip Girl because she states in her final column, “I thought about making complicated plans to take a bunch of friends out to the beach in Sag Harbour in my exquisite new European-import car.” We get told earlier in the book that Blair received an imported car from her gay father in Paris. However, this might be pure coincidence as Blair might not have been the only graduate on the Upper East Side to receive a European car. One contradiction, though, is that Gossip Girl stated her birthday in "Because I’m Worth It". Blair’s birthday is in November, and Serena's birthday is on Bastille Day in July, and "Because I’m Worth It" is clearly in February, they can't be Gossip Girl. However, Gossip Girl also noted that it may or may not have actually been "her" birthday.
