Thirty-four-year-old writer Audrey Beacon is grieving alone during lockdown when a post about a bookshop for sale in upstate New York pops into her social media feed like a lifeline.

While reviving the shop, Audrey discovers letters from the 1950s between the previous owner, magazine writer Evelyn Cabot, and a local librarian, Hazel McIntyre.

Will Audrey find the courage to heal the wounds of the past --- including her own?
