I have been a fan of Diane Chamberlain for years! This book blew me away. She quickly threw us a twist that was completely unexpected - Time Travel! We follow two main character in the mid 1960s - Hunter and Caroline from the time they meet. Caroline is a physical therapist for Hunter and immediately knows he is perfect for her sister. We fast forward a bit to shortly after Caroline's husband is killed in Vietnam and she finds herself pregnant. The baby is not doing well and Hunter knows exactly what must be done - send Caroline to the future so her baby can get the surgery it needs to survive. I am beyond impressed with how easy it was for me to fall in love with these characters and be completely invested in the story. The writing grabs you from the start and you are in for quite a ride.
