By the half way point, I hated all the characters. They were all cheating, lying, bored housewives. The only one I actually liked was the husband and the little girl (mainly because I felt sorry for them). I was honestly glad they all died. They were dense and oblivious without common sense. Also, if you are going to write a book about murder you might want to research a bit about forensics before writing a book. Blunt force trauma to the back of the skull is obviously not self inflicted and would be noted in the autopsy. I was expecting a gritty crime story and instead, it was a "who done it?" book. The author should have spent less time researching pregnancy and more time researching true crime, forensics, blood spatter patterns, defense wounds, and character drive and motivation. Make characters likable and relatable, not selfish and self-absorbed. And give them a bit of common since... "What are you doing with that hammer?" ... building a tree house, what do you think?
Cringe, cringe, cringe. Character dialog better in the original Resident Evil game.
The only thing that kept me going till the end was wondering what would happen to that little girl. And the fell flat at the end. Hours of my life I will never get back.
