The Sun Collective by Charles Baxter

Set against the backdrop of a politically and socially divided Minneapolis, this novel weaves together the lives of a retired couple, Harry and Alma Brettigan, who are searching for their missing son, and a young couple, Christina and Ludlow, who become entangled with a mysterious activist group known as the Sun Collective. As the characters' paths intersect, the narrative explores themes of disillusionment, the search for meaning, and the blurred lines between activism and extremism, all while questioning the nature of community and the lengths people will go to in pursuit of their ideals.
