In my opinion this story is a little bit weird and travel throw the time in some part of book and may reader feels confusing.
As generally speaking this book tell a story about an iranian's family which they haven't enough understanding with each other and it comes from dad's behaves with one of his son who called Aidin.
Aidin wants to be a poet and study lectures in university of Tehran but his dad is in opposite side of he and forces him to work at nut shop.
At the end he escape and horrible events happen one after one. On the other hand OrhAn his youngest brother is take after dad and do like he.
