40 Years Old is not only a romantic novel; it is also about the middle-aged crisis of a married woman. It's about the fear of aging, loss of vitality and youth, and longing for lost opportunities. Meeting the love of her youth and letting her heart pound, just like in her twenties, is the origin of these rising emotions. References to the situation of Iranian society in the 1990s are another part of these book strengths. 40 Years Old has been translated into English, and an Iranian film with the same name was made in 2010 base on its story. Alaleh is the main character of the novel, and she is on the verge of her forties. She lives with her rational and kind husband and his happy and cheerful young daughter. Alaleh is employed and has a quiet and good life. But this peace is shattered by the news; her love of the twenties, who has been immigrated years ago and is now the conductor of the orchestra, is scheduled to return to Iran and have a concert in the same hall where she is in charge. At the same time, as recalling the memories of that love, a flood of different emotions rushes towards Alaleh. She is looking for a 20-year-old girl inside herself who was a lover and the excitement of her youth, and as more she searches, the less she finds. Alaleh has been flipping through the past twenty years to achieve something that is her own, but she does not find it and becomes frustrated. The apprehension of encountering her previous love and the fear of having a feeling for him again complicates the situation. This is an excuse for Alaleh to do something strange at the age of forty. The same strange thing that, in her own words, happens to every woman in her forties to prove that she is not old.
