It's been a long time since I've bawled like a baby over a book, so when I started this book, I was nowhere near tears. I think it was the narrating of possible alternative universe scenarios that got me. When Ike and Charlotte (who can't touch each other, because he'd dead, and she can see ghosts) start roleplaying a future where they can get married, have a baby, hike, have lazy evenings in front of TV, but knowing it can never come to be pass...gah, it caught me right in the feels. I was sobbing for five minutes straight. (Hey! That's a lot, ok?) 
 Due to that scene alone, it elevated this to a five star read to me, otherwise I'd just have toyed with giving it a four. Really packs an emotional impact. You would have to have a heart of stone, not to cry at this one.
