Irritating one first, by Sophie Hannah, Little Face. 2006. Totally awful main character, whiny and miniuplative, no redeaming features. Skipped the last 3rd of the book and thought the ending was a waste of time.
Two of the three books that Angela Clarke has written. Very good mysteries. Characters are believable and likable. Just started the third book. Lots of social media built in - they are called the social media mysteries.
1. Follow me, 2015
2. Watch Me 2017
3. Trust Me 2017
Enjoyed them and hope she writes more.
Quicksand, 2017, by Swedish author - Malin Persson Giolito. good plot, you really don't know what she did or did not do until the end. Interesting study of a school shooting
