Wow, I am blown away by this book. As the blurb of the book states, "When you read this book you will make assumptions." Just when you think you know what is going to happen or be revealed, your thrown for a loop. All is not what it seems and each character's behavior stems from the childhood and lifestyle and the decisions they make set off other chain of events. So much deception and subtefuge, intrigue and mystery with all of the characters, Vanessa, Nellie, Richard, Maureen, Emma and Kate. The Wife Between Us was thrilling and I have questions and would love to know more about siblings, Richard and Maureen. Loved the ending and I look forward to reading future books by these two authors.
