Ruth Winters is retired, widowed, and resigned to spending the rest of her life alone in her suburban home. She likes her routine and uses it to avoid having to spend time with other people. She probably wouldn't call herself fulfilled, but it's too late now to go chasing happiness.
Then three things happen at once: a beloved niece makes a big announcement, an old flame reaches out, and her estranged sister receives life-changing news. Ruth finds herself reconnecting with people she thought were long gone from her world, as she is forced to reconsider her expectations for this phase of her life.
None of this fits into Ruth's routine--in fact, the whole thing just blows to bits. But when Ruth starts to pick up the pieces, she discovers that maybe it's not too late to make something new after all.
