Dominique Morisseau is a Haitian American playwright, who was raised in Detroit, Michigan. She’s written extensively about her native city, but her newest, and perhaps most autobiographical, play shines its light on the island nation where her father was born. It’s called “Bad Kreyòl”, and it looks at a pair of cousins — one from America, the other from Haiti — negotiating a difficult relationship. Jeff Lunden reports from New York, where the play premiered.
