This was a recommendation from a coworker and WOW I'm very glad I read it. (Listened to it) 
The story is amazing, and the characters painted so wonderfully. The timelines both moved seamlessly-- I've read books with multiple timelines that try to get little cliffhangers and make you want to stay in one timeline more than the other, but this one did a good job of weaving two stories into one. I loved the narrator as well. 

I honestly think I would have loved it just as much if the fiancés had not both come back at the end, as the mother/daughter/granddaughter relationships were so beautiful. But it was heartwarming to have the extra happy ending, and didn't take away from the story at all.
