Gossip Girl, Psycho Killer

Gossip Girl, Psycho Killer - Cecily von Ziegesar After reading the GG series in high school this Psycho Killer edition caught my interest. Slightly disappointed it was mostly secondary and other random characters who died. I read that this Psycho Killer was suppose to be the end of the series and am a little confused at the cliffhanger. Also the killing was so random, out there and not really planned. A little disappointed that everyone seemed okay with it and nobody really had to cover their tracks.
