The novel's title is taken from a quotation at the story's conclusion, when Susie ponders her friends' and family's newfound strength after her death:
These were the lovely bones that had grown around my absence: the connections—sometimes tenuous, sometimes made at great cost, but often magnificent—that happened after I was gone. And I began to see things in a way that let me hold the world without me in it. The events my death brought were merely the bones of a body that would become whole at some unpredictable time in the future. The price of what I came to see as this miraculous body had been my life.
