Best known as the Caribbean Nightingale Poet, she published her first collection of poetry, The Nightingale's New Song: A Black Woman's Poetic Notes, the first book in a series. This first volume traces Martial's healing process through several heart-wrenching experiences: the death of her infant daughter, past domestic and sexual abuse, and other traumas that she's fought her way through. It also served as a way for Michaëlle to process her mother's diagnosis of early onset Alzheimer's, a diagnosis that was given during the most tumultuous years of her life.
