Therefore, the new Gossip Girl series, which is meant to start immediately after the previous, should start at latest in the summer of 2004.
Therefore, there should not be such glaring errors such as: stating that a character is carrying around a dog-eared copy of a book that doesn't come out until 2006, or using technology that doesn't come out until 2007 or 2008.
There were plenty of errors that started happening right around when the series started being ghost written instead of being written by the original author. Now there seem to be plenty more.
I guess the only way to enjoy it at all is to just pretend that the year in which the books are set keeps changing depending on the book you read. How completely daft. Then again, I'm about to turn 31 and I am reading a book meant for a teen girl. Go figure.
