What is the author's style in Praisesong for the Widow by Paule Marshall?

The story follows the journey Avey takes from the cruise to the island, and to the Big Drum Ritual chronologically, and laces that chronology with visits in memory into Avey's past. In the flashbacks, the stories are told just as vividly, still written in the third-person limited omniscient, so that the result is a complete telling of the formative experiences from Avey's life, told in snippets as their subject matter applies to what Avey is experiencing in the Caribbean. That storyline is then divided into four parts. The first, called "Runagate" takes Avey from the ship to her hotel room on the island, and includes the stories about her great aunt, her physical symptoms of unrest on the ship, and a bit of introduction into her life with Jay in both its poverty and its comfort.
