Which book features a deep analysis of race relations in America?

The choice that features a deep analysis of race relations in America is "The Invisible Man" by Ralph Ellison. This novel explores the complexities of African American identity and the social challenges faced by Black individuals in a racially divided society. Through the experiences of the unnamed protagonist, Ellison delves into themes of invisibility and the quest for self-identity amidst systemic racism. The narrative not only recounts the struggles of the main character but also critiques the broader societal structures that contribute to racial inequality.

In contrast, other works, while significant in their own right, do not focus primarily on race relations in America. "Madame Bovary" addresses issues of desire and societal expectations in 19th-century France, "Lord of the Flies" examines human nature and civilization versus savagery in a group of boys stranded on an island, and "The Great Gatsby" critiques the American Dream and social stratification in the Jazz Age. Each of these novels presents important themes, but none directly engage with the intricacies of race relations as profoundly as "The Invisible Man."
