This is a very good story of alien contact. It seemed to me to be talking about two alien biosphere's, the one that dropped from space and the one that Nigeria represents to an old white, dude like me. The narrator is unreliable and somewhat unlikeable and the story is told in a non-linear time line. The story is very much grounded in its sense of place and is much an afro futurist viewpoint as a novel of first contact. Recommended but I am not going to jump to the next one in the series with any great speed as there is just too much other good stuff to read.
