What is the author's style in A Bend in the River by V. S. Naipaul?

A Bend in the River is divided into four sections: The Second Rebellion, The New Domain, The Big Man, and Battle. Part One: The Second Rebellion introduces the characters, brings Salim to his new life, and shows a brief guerilla uprising stopped by foreign mercenaries. Part Two: The New Domain describes the rebuilding of the town, including the President's grand plans to make the area outside town represent the best aspects of the new, modern Africa. Part Three: The Big Man shows the President tightening his grip on the country. An "authenticity" campaign begins to make the country seem more African. Meanwhile, in Salim's village, personal lives begin falling apart. Part Four: Battle relates both to Salim's struggle to leave Africa and the rebellion that will soon throw the country into political chaos.
