Maurice Carlos Ruffin’s debut novel “We Cast a Shadow” is set in an unnamed Southern city in the not too distant future. American society has become more racially restrictive. To avoid the various prejudices suffered by Black people, some resort to “demelanization”, a painful procedure that removes physical traits associated with Black people. The book is a slightly off-beat dark comedy about a nameless narrator who goes to desperate lengths to shield his son from this race-based dystopian society.
