Oh wow. When I first start a book, all I want are characters that I will like. I didn't like a single character in this book but I've still given it 5 stars. 

Jane Harris is a self absorbed, delusional, manipulative narcissist and you just love to hate her. I love how the story is written, as though Jane is speaking to the reader. It's like you are inside her brain and you are brought along with each lie she tells and her true inner thoughts. 

Jane is mother to Betsy and Mary, who has died after accidentally falling off a cliff, and wife to David. Betsy doesn't have a great relationship with her, David is cheating on her and she spies on them through apps and trackers. She makes it seem like everyone is against her, she's the victim. The pace is great and Jane is waiting for the culmination of events, the truth coming out (well, her version of the truth), so it makes you want to quickly read on to see what will happen.
