Siblings survive their artist parents

Just finished a book that might appeal to bookclubs that enjoy something a little quirky, like Miriam Toews or Jessica Grant characters.  The Family Fang by Kevin Wilson is the story of a family of performance artists.  Caleb and Camille are completely devoted to their art.  They enlist their children Annie and Buster (called A&B) in their disruptive performances.  It is comic and painful at the same time.  It could lead to some interesting book club discussions around what exactly is art, and where is the line between being a professional and being a parent drawn?
