Like in his earlier works, TD Ramakrishnan takes a lot of liberty in presenting historical people as characters in his novel - Many of Africa's political leaders and dictators come as characters in this novel. In the style of narration, the book is very similar to Francis Ittykkora and Sugandhi Enna Andal Devanayaki - all of them have a mix of history, fantasy, "constructed" myths, elements of mystery and descriptive sections on exploitation and torture.
The author has been successful in providing a balanced outlook on various aspects, as presented from the perspective of Thara. Her transition to being a "lover" of Idi Amin would surprise us first despite the justifications she gives through her dream interactions with "Mama", though in hindsight we can see that she just matches other female characterizations by the author in his earlier works. Thara later gives some thoughts on validating the egoistic behavior of the dictator with references to the oppressed past of the African people. This approach of "looking at both the sides" is seen while discussing about the involvement of Soviet Union in African Politics as well. Though Mama Africa makes several subtle statements on various social and political aspects of the region, I would prefer to look at it as just a story book, and I enjoyed reading it.
