The book "And the Mountains Responded" by Khaled Hossein

On a dusty road to Kabul, two children, a brother and sister, spend their last hours together. Then, as if nothing had happened. No one will ever remember Pari, happy in her brother's care and love. Abdullah won't forget. Her sister won't remember. The following years of their lives will be marked by stories of devotion, cruelty, and return, while life in Afghanistan will be full of catastrophic twists and turns.
