Miranda July’s novel “All Fours,” described as the first great perimenopause novel, follows a woman in her 40s who embarks on a transformative road trip, only to pause for three weeks in a motel to reevaluate her life. The book quickly gained popularity among women over 40, becoming a cultural touchstone and prompting July to create a Substack and a mini-series. Reflecting on her creative process, July emphasizes the importance of discussing personal changes, advocating for conversations that spark creativity and self-discovery.
