But it’s not all grief. Letters to the Lost was also funny and cute, I mean really cute like I was clutching my heart and squealing like a literal 6 year old and im not even ashamed about it I’m about to turn him down, but then I look at the cookie. I was expecting something basic, like sugar or chocolate chip. This looks like a miniature pie, and sugar glistens across the top. “What . . . is that?” Please know I’m thinking of you and your little boy today and every day. He will forever be in my heart. The letter-writing aspect of the story was so wonderful. At first it was odd - Juliet was furious to find out that someone wrote on her private letter to her dead mother. But then the letter-writing turned into something more meaningful and necessary. Both characters had a lot of pain and hurt to work through, and the anonymous letter-writing really helped. Imagine being able to lay out your big problems, your little problems, your crappy day, to someone who knows exactly nothing about you. Someone who knows nothing, and yet everything. Letter-writing isn't new in YA (P.S. I Like You by Kasie West, Tell Me Three Things by Julie Buxbaum...), but it's a concept that I adore so much.The letters they wrote to each other were so thought provoking. Many of them gave me chills and shivers. There's a raw honesty to opening up to someone who doesn't know you but that you feel you can trust. It's like you bare your soul without fear of judgement. Each letter had weight, if that makes sense. They just conveyed so much. Besides compensation or replacement of the lost item, the receiver wants to hear the steps you’ll take to prevent a repeat of the loss.
