Read it in French. Based on a real story.

An extremely sad read... Incredibly well written though.
Written by a mother whose daughter suddenly becomes frail and dies in a matter of a few days. This book depicts all the grief that parents go through when they lose their children and how people try to find some coping mechanisms, whether it be preparing for the funeral, looking into all possible causes of death, writing a diary, talking to your dead child as if she were alive...
