This collection investigates how non-religious individuals can navigate, celebrate, and find meaning in the Christmas season without adhering to its traditional theological underpinnings. Edited by Ariane Sherine, the book compiles essays from a diverse array of prominent atheists, scientists, and comedians. The contributors provide personal anecdotes and philosophical reflections to argue that the cultural and communal aspects of the holiday remain valuable even when stripped of supernatural claims.

The book is regarded as an accessible and lighthearted contribution to secular literature, focusing on the practical and social dimensions of holiday participation. Its collection of varied voices provides a broad spectrum of approaches to the season, ranging from the purely cynical to the warmly celebratory.
