The sister wrap up Where the Crawdads Sing by Delia Owens (chapters 45 - 57).  They finally can talk about who dunnit and honestly dive into some deeper discussions about right and wrong and America's justice system.  All of this is cut by sisterly shenanigans and general silliness. 

The next book they will tackle is The Flatshare by Beth O'Leary!  The first assignment will be chapters 1 - 20.
