City of Night explores the life of a young, unnamed narrator as he navigates the underground gay subculture of 1960s America. Set against the backdrop of major cities like New York, Los Angeles, and New Orleans, the novel follows his experiences with a series of characters who embody various aspects of LGBTQ+ life, from street hustlers to high society figures. Through these encounters, the book delves into themes of identity, sexuality, and the search for personal meaning within a marginalized community.

City of Night has been banned and challenged due to its explicit depictions of sexuality, drug use, and the gritty realities of urban life. The novel’s candid portrayal of LGBTQ+ themes and the complexities of the gay subculture were considered controversial and inappropriate by some readers and institutions. Its frank exploration of homosexuality, combined with its explicit language and sexual content, led to its removal from certain libraries and educational settings, where it was viewed as offensive or unsuitable for younger audiences. Despite these challenges, the novel remains an important work in LGBTQ+ literature.
