This is exactly what the title says. This is a parody of the first book in the Gossip Girl series, but the weird thing is that the parody is written by Cecily von Ziegesar herself. I find this both courageous and extremely weird. It must feel uncomfortable to butcher your little baby book. Gossip Girl, Psycho Killer is heavier on the killer part than the Gossip Girl part. All the original characters are in it: Blair, Serena, Chuck, Nate, Jenny and Dan. The book loosely follows the original storyline, but adds massive slaughters and gross murders. I have to say, this book is pretty gruesome. If you're not interested in horror, or if you are squeamish for blood or severed heads, don't read this. This book isn't really for hard-core Gossip Girl fans, it's more for the fans of cheap horror flicks. I personally actually quite like horror. But even for me this was a little bit too much at times. It took me a very long time to get into the book, and to get into the dark humour. In the end, it was entertaining, and the adaptation from the original novel was very well done. I would recommend Gossip Girl, Psycho Killer but with a fair warning.
