Fran, an aging but energetic expert on elder housing, drives around the English countryside visiting facilities and also friends and family.  She, herself, is not at all ready to go gentle into the good night so many others are facing.  But everywhere she encounters reminders of mortality--her son's fiancee suddenly dies; an old friend is dying a lingering death of cancer; others in her circle of family and friends are facing their own or others' mortality in various ways, including natural disasters like earthquake and flood.  The episodic story takes place in England and in the Canary Islands; the large cast of characters are linked by intersecting stories and by their mortality, of which they, and the reader, are recurrently reminded.
