Artist and avid reader Karen Moss felt overwhelmed by the never-ending news of book bans happening all across the country. As she’d previously done in addressing other social justice issues, Karen used her canvas to make a statement — this time, intimate portraits of her loved ones and their favorite banned books. The portraits are showcased in a new exhibit at the Boston Public Library’s central branch. This is the latest edition of  “Unbound Pages,” our year-long series on the book-banning movement in America.
