Tucked away in a quiet corner of Cambridge sits a shop filled with charming stationery and exquisite pens. Here Clara Cohen performs her particular type of magic, writing life-changing letters to strangers in need. Clara understands the transformative power of correspondence, so when she uncovers her great-grandmother's wartime love letters, she embarks on a profound journey to Amsterdam in the hopes of healing the tragedies of the past and, in doing so, change her own future.
