Great ending!
A woman lost her son a year ago. He was taken from their home sometime in the night. Her husband left her and is with a new woman who looks like her and also looks like his previous wife, who is now deceased. Two-thirds into the book, it’s revealed that the police and mostly everyone else suspects that the kidnapper was someone inside the home. The uncertainty of whether or not the main character can be trusted or if she’s unreliable makes it more interesting and I thoroughly enjoyed the ending, 4 stars!
