Persepolis

Adult comics can often invoke themes of adult ideals, and imagery with subject matter that shouldn't be recommended for children. European comics gave this off more than graphic novels written in America, and these comics could range from themes about humanity, to sex.
However one trait a lot of these comics have is that they tell personal stories, and the struggles of living in radically changing worlds. One example of this is the graphic novel Persepolis, which was adapted into an animated movie. In this novel, writer Marjane Satrapi writes about her life experiences growing up during the Iranian Revolution in the 1980's.
In this story it deals with Satrapi growing up living her life as a woman during the nations most infamous time. Learning the hardships of Sexism, life and death, and the meaning of losing what means the most to you.
The comic is split up in two parts, where is tells about Satrapi's childhood to teenage years living in Iran, and the second volume tells about her experiences living outside the nation, and finding her place in the World.
As a whole the entire volume series of Persepolis is very mature themed when it comes to telling stories about living in a changing world, as much as it is about the hardships of womanhood in Iran when once upon a time, it never had its problems like this before the 1980's. Yet that's why the story is so well told even today, as it will stand the test of time as a cautionary tale of taking your life for granted, and having it disappear so quickly.
