I loved this book; however, half of the book club did not. Some thought it was poorly written and did not make sense. They did not appreciate the spiritual nature of the book, as I did. I loved the ghosts and the whole idea what might happen after we die. All said, we had a wonderful discussion about these issues and the relationships between twins. We also loved the quirky character of Martin. Niffennegger knows how to spin a tale that is "out of this world!"
