I found the writing style of this one, quite interesting.. The whole thing is narrated through refrigerator notes that mother and daughter leave for each other. You get to learn how their relationship is and what problems they face.
(I don't know about you, but I never communicated with my mother like this. Plus, our refrigerator door isn't magnetic)
Upon finishing this in one sitting, I wasn't very fond of the story, as it added drama just for the shake of drama. It was just too predictable without adding its own flavor.
