This book investigates the complex and often contradictory ways that sexuality and intimacy were understood and experienced in nineteenth-century America, particularly through the lens of what the author terms 'the untimely.' It examines how notions of sexual development, desire, and social norms were frequently out of sync with lived realities, creating a unique cultural landscape. Coviello draws on a wide range of sources, including literature, personal correspondence, and social commentary, to explore how individuals navigated these temporal dissonances in their personal lives and in the broader cultural imagination.

The book is recognized for its nuanced exploration of sexuality and temporality in the nineteenth century, offering a fresh perspective on historical understandings of intimacy. Scholars have noted its insightful analysis of how individuals grappled with social expectations that often lagged behind personal desires or developmental stages. The work is appreciated for its engagement with a diverse array of primary sources, providing a rich and detailed account of the period's cultural landscape. Its contribution lies in reframing historical discussions of sex and desire through the concept of temporal dissonance.
