Omparison between Light in August and Dangling man

I need an essay making a comparison between Light in August by WIlliam Faulkner and Dangling Man by Saul bellow. It is a free topic but we should focus on gender, class, racism or any interesting topic related with the 20th and 21st century American Literature and these two books. Moreover, if it is posible to add any interesting secondary source that would be also important.
