This is beautifuly done. It is subtle at the beginning, and if you read it too quickly, I think you'll miss the emotions behind the story. Lee takes the reader through the emotions of grief, both from the perspective of someone who has died too soon and from the family and friends they left behind. All of the elements work so well together, flipping between Kit and her family. I appreciated the use of color to distinguish between the two, making it easy for the reader to follow. 

The art itself is somewhat simple in nature, but Lee is still able to portray so much emotion in her art. It's truly such a lovely graphic novel, and one that I'd recommend to everyone.
