In Brookfield, the local Board of Education faces a contentious decision. A group of community residents has challenged the presence of the book “Fun Home: A Family Tragicomic” by Alison Bechdel in the high school library. The board’s previous ruling to retain the book is now under scrutiny. Tonight at 7 p.m., the Board of Education convenes in the Brookfield High School Media Center to revisit last year’s recommendation by the high school special committee.
