In Emma Copley Eisenberg’s new novel, “When Bernie and Leah Travel the Great Perhaps,” two aspiring artists embark on a cross-country road trip that fosters a profound connection and self-discovery. Through their shared experiences, Bernie, a photographer, and Leah, a writer, navigate their identities, find inspiration in their art, and challenge societal norms around body size and queerness. Drawing inspiration from Patricia Highsmith’s “Strangers on a Train,” Eisenberg creates a narrative driven by the transformative power of intimacy and connection that unfolds during an extended journey.
