Nothing Can Keep Us Together is the eighth installment in the original Gossip Girl novel series by Cecily von Ziegesar. It is also the last in the series, before It Had to Be You, to be written by von Ziegesar herself.
Blair meets Marcus, an attractive English lord. Ken Mogul is back as he is directing a modernized version of Breakfast at Tiffany's 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 this, 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.
