This is tough, I'm torn because I liked the 1st book, despite some of the grammar/syntax issues. However, I've found this one painful to read for a variety of reasons, all of them personal. My first clue that I was not as engaged in this story was the fact that I keep putting it down to read fan fiction or anything else that could engage my mind fully.
The timeline indicates that the story takes place two years after the 1st book but there has been little if any character development. That combined with the general feeling that I was re-reading the 1st book, as if the formula worked for the 1st so with a few changes its been reproduced in the 2nd.
Needless to say, no matter how gruesome the murders I personally got bored and lost interest in trying to figure out who the murderer was or the why behind the murders.
