I have listen to the audiobook twice now once before, I knew it was going to be a movie and the other just recently.
I love the characters both the main (Alex and Henry)and supporting characters are a joy to get to know. It's also very romantic at one point through their emails, Henry and Alex put lovers throughout the ages.
It's the kind of story that you really can read or listen to time after time. As I said the last time, I listen to it, I was laying on my bed and tears were rolling from my eyes into my ears. Happy tears, emotional, tears you genuinely get to love these folks
