The Love Song of Miss Queenie Hennessy (Harold Fry #2)
Rachel Joyce

A new volunteer at the hospice suggests that Queenie should write again; only this time she must tell Harold everything. In confessing to secrets she has hidden for twenty years, she will find atonement for the past. As the volunteer points out, 'Even though you've done your travelling, you're starting a new journey too.'
Queenie thought her first letter would be the end of the story. She was wrong. It was the beginning.
