I felt the same way about Social Suicide - it was fun and I loved solving the mystery of who killed Sydney Sanders. There were a few things that irked me - a lot of running around and red herrings. I mean, I loved that I did not see the ending of Social Suicide coming AT ALL. Not in the slightest bit. And I was super impressed afterwards, because the idea hadn't even occurred to me. But all the running around and interrogating Hartley did in Social Suicide left me a bit tired.
I definitely liked Hartley a lot more in Social Suicide than I did in Deadly Cool. I felt like I related to her a lot more - she had real moments with her mother and her friends that I know most teen girls feel at some point. Plus she seemed to pick up the trail a lot quicker than in Deadly Cool, despite all the red herrings. I didn't like Chase as much as I did in the Deadly Cool, though. He bugged me and not in a good way. I'm curious to see where their relationship will be in the next book - because there will be a next book, right?
My only real complaint, besides the circles and Chase, was that the stakes in Social Suicide didn't seem to be as high as they were in Deadly Cool. I mean, stuff happens and of course lives are threatened, but it didn't seem as tense to me as it did before.
But in the end - if you guys are looking for a fun YA mystery that's relevant and relatable (in some ways), definitely check out the Deadly Cool series by Gemma Halliday. I'm a Nancy Drew fan girl for life, but Social Suicide was certainly an enjoyable mystery and I can't wait for the next book!
