This is a book unlike any I have ever read before. Once you manage to wrap your head around the time frame changes it is excellent. It is based on a new and interesting premise of time travelling as a kind of genetic disease. It follows a man and his wife as they interact over many years at many different ages. It shows all the trials and tribulations that are faced by anybody in a relationship and the unique difficulties faced by being in a relationship with a time traveller. It is a winning combination of fantasy and romance. You can't go wrong with this book.
