Essays / A Thousand Splendid Suns thesis: the female protagonists have to sacrifice their youth and freedom.. [2]

I was given various theme topics for the book "A Thousand Splendid Suns" and I decided to choose the topic sacrifice to make a thesis out of. My thesis is :

In the book A Thousand Splendid Suns, the female protagonists have no choice but to sacrifice their youth and freedom in the circumstances they are given as proven in the book through violence, poverty, and role in society.

Does my thesis present a valid argument? Does it make sense?
