The Lying Game Book 2: Never Have I Ever

Emma might have just landed herself right where she needs to be and wants to be, which is close to finding out the truth about her sisters murder. With The Twitter Twins constantly trying to get her attention, the killer is sending her threats about stop digging or she'll be next. Emma thinks that the Twitter Twins are the killers because of what happened to Gabby (one of the Twitter Twins) on the night of the train track lying game. However, Emma finds out something completely unexpected and also finds someone completely unexpected at the end of the second book.
If I say anymore, it will destroy reading the second book, so I'll leave the summary at that. The second book opens up a whole other door, and Emma's attraction towards Ethan is getting stronger. Now that Ethan knows that she's not Sutton, they both have teamed up to find out who killed Sutton. 
 I must add that reading the books make me feel like I'm reading a completely different story than what I'm watching on ABC family. I prefer the books over the television show in any given day. Also the books make more sense as far as the story is concerned than the show. The show focuses more on the drama than the actual story. I would have loved seeing The Twitter Twins in the show and the books. I wish TV would stay true to the books.  

Emma is definitely the opposite of Sutton. However, after her death, Sutton is realizing just how horrible she was. Emma's character is strong, and she makes some great decisions. After Emma took over Sutton's life, things have become better around the Mercers house. A lot of Sutton's friendships have improved and Ethan is secretively making his way into Emma's life. However the tension still remains, and the killer is still loose. How long before the killer makes Emma play Never Have I Ever truthfully?
