This is one of these books that require a little "mourning" period after reading. You can't just pick up another book after turning the last page. I had settled into the character's lives and needed some time to let go. 
 Deep down, I know that I would have been disappointed if (view spoiler)[it had worked out for Sadie and Jake. It would have felt a little too "Disney". But man, I was very upset that Sadie got shot, and then that Jake made the decision to reset history and delete their relationship. (hide spoiler)] 
 Great read
