This was an ok read. Cass drives through the woods during a storm and sees a woman in a car by the side of the road. Cass isn’t sure if the woman’s car is broken down or in some kind of distress. Not wanting to get out in the pouring rain, she stops and waits to see if the woman asks for help. When she doesn’t she drives off and goes home. The next day she finds out the woman had been murdered. Too afraid to tell the police she saw the woman but didn’t stop to help, guilt starts to eat away at Cass and affect her relationships in her life. To compound the problem, she starts having memory problems and fears she is showing signs of the dementia that killed her mother.
The angst and anxiety spiral that Cass falls into goes on far too long in the book and drags it down. About 1/4 of the way through the book I already knew what the twist would be and the story was very predictable after that. This is not the author’s best book.
