Essays / Comparative Essay - Woman at Point Zero vs. Death and the Maiden [2]

Hello,
I am in the process of writing a comparative essay on Woman at Point Zero by Nawal El Saadawi and Death and the Maiden by Ariel Dorfman. The aspect I am analysing is self-respect within the protagonist in each book.

At the moment I am having trouble finding a common ground with which I can compare and contrast these two works. Does anyone have a suggestion?

Thanks in advance.
