In the tragicomic 'Loving Day,' Mat Johnson tells the story of Warren Duffy, a man who inherits a dilapidated mansion in Philadelphia following the death of his father. His return to America is marked by a series of disillusionments: a failed marriage, career troubles, and the unexpected discovery of a biracial daughter he never knew existed. As Warren attempts to rebuild his life and connect with his teenage daughter, Tal, they navigate the complexities of race, identity, and family legacy. Their journey takes them from a haunted house rich in history to encounters with a mixed-race cult, culminating in the chaos of Loving Day - an unofficial celebration of interracial love. A blend of sharp humor and poignant reflection, Johnson's novel explores the multifaceted dynamics of fatherhood, self-acceptance, and the dichotomy of black and white identity.
