Pippa Lee--a fifty-something third wife to the publishing lion Herb-- moves with her 80-year old husband into a retirement community after liquidating the trappings of their Manhattan life before Herb finds himself further and further along the path to decrepitude. Pippa is a doting wife, supporting her artist husband, who expects it. Their grown children, Grace (a photographer) and Ben (a soon-to-be-called-to-the-bar lawyer), are interesting and interested.
I enjoyed the witty repartee of the present in the novel, but found the flashbacks to Pippa's past where she worked as a model for an S&M lesbian filmmaker trying a little too hard to be hip.
The novel is currently in development as a film starring Alan Arkin, Julianne Moore and Winona Ryder, directed by Rebecca Miller. I am curious enough about the adaptation to go and see the movie when it's released.
