I had avoided this for a long time because I thought it'd be too depressing, but it wasn't that so much as really tense at the beginning, knowing already how it ends (somewhat) but not knowing how. I enjoyed seeing the situation from Jack's perspective, though it did allow the author to not have to delve into an adult's more complex feelings (which would be really hard to do). 
 Ready for the movie now. Read for the Read Harder 2016 challenge.
