The Love Song of Miss Queenie Hennessey, by Rachel Joyce

Companion piece to The Unlikely Pilgrimage of Harold Fry, Love Song lets you know what Queenie is up to while she waits for Harold to wend his way across England.  She is dying inexorably in a hospice facility that makes you want to think better of hospice.  Her lovely letters to Harold talk about the staff and patients at the facility but also reveal the sad love story of Harold and Queenie.
