The Light Between Oceans by M.L. Stedman
I didn't realize this book was being made into a movie when I read it. I'm glad I didn't because I always visualize the actors instead of letting my imagination conjure their appearance. This is a heartbreaking story, but hearts can be mended in some situations, although it is difficult to imagine how they ever could be. I have wanted to go to New Zealand since Lord of the Rings, but now I want to see this movie, then go.
Tom and Isabell are living a perfect life, except for their desire for a child. The decisions they make lead to a haunting tale that the reader will consider long after they have finished the book. Questions are raised about when you tell the truth and after a deception, what then? The dilemma challenges the couples relationship. It also raises the question about returning a child to it's biological family after the child has identified others as the parents. The results are heart wrenching. The fallout is not just the immediate family, but grandparents and friends. Only after that child becomes an adult can they identify with the motive and feelings of those around them when they are children.
This story is beautifully written with well-developed characters that the reader immediately relates to. I highly recommend it.
