Premise: New Day is a 1949 book by Jamaican author V. S. Reid. It was Reid's first novel. "New Day" deals with the political history of Jamaica as told by a character named Campbell, who is a boy at the time of the Morant Bay Rebellion (in 1865) and an old man during its final chapters. It may have been the first novel to use Jamaican vernacular as its language of narration.
Hypothesis: New Day was written by an African author.
