What happens when someone changes the way you see the world—but doesn’t stay in it? This quietly tender memoir-like novel unfolds across twelve months, from June to the following May, tracing one woman’s journey through connection, longing, and quiet transformation. Each chapter is named after a month—marking not just the passing of time, but the slow evolution of feeling, grief, and growth. Written by Estelle H. Lee, an analog circuit designer and lifelong observer of subtlety, the book began as a private a way to process a season of unexpected love, emotional awakening, and the kind of loss that doesn’t come with closure. Combining the precision of an engineer’s eye with the sensibility of a storyteller, Estelle crafts a narrative that is intimate, lyrical, and emotionally resonant. Set against the vibrant stillness of Bali, the noise of city life, and the quiet gaps between two hearts across the globe, this is a story for anyone who’s ever loved deeply—even briefly—and found themselves changed because of it. It speaks to those who have wandered through careers, cities, or relationships, looking for the place where they might finally feel like themselves. Analog Heart in Digital Days is for the readers who linger on sentences, who find themselves awake at night recalling the sound of someone’s voice, who have both science and softness living in them. If you’ve ever felt like a stranger in your own life—or rediscovered your heartbeat in someone else’s presence—this book might be a quiet companion to your own wandering.
