When a mysterious guide, Lucas, draws her into the hidden corners of the city, she discovers a world of shadows carrying secrets, memories, and untold truths. Tasked with uncovering the lives people hide, Mia confronts living shadows, pieces together stories of danger and courage, and learns that seeing and recording the city’s unseen threads is both a burden and a purpose.
