This one took me a while, but I'm glad I took the time to read it. The story is told around two half-sisters who grow up not knowing of each other's existence. They have very different lives with one having a seemingly fairytale life and another struggling with a potentially terminal illness, a collapsed marriage, the loss of her mom and best friend, and trying to decide if she wants to fight for her life by looking for a kidney donor. They find each other through a DNA test which ends up with pain and betrayal, unearthed secrets, but also a chance at sisterhood that neither has ever had the opportunity to have. Even though it took me a long time to read this book because of outside circumstances, I never forgot what was going on or who everyone was, and I would quickly become immersed back into the book until I was interrupted yet again, lol! I really loved both sisters for different reasons, and I found their connection to be believable and found myself to be empathetic to both. This book covered so much about family relationships, what marriage can or should look like, how you can love people and still hurt them, but how you can also forgive even the most painful of hurts. I also appreciated all the research the author did about kidney transplants and the perspective of both the donor and the recipient, and how complicated it can all be. I also adored Janie, Sela's nurse, as well as one of the other donors that Caroline met on her journey. I would have loved listening to this as an audiobook, but also enjoyed reading it on my own. I would be interested in reading other books by this author.

I received an advance review copy for free, and I am leaving this review voluntarily.
