Black Panther

Honestly, the story is just plodding. You get the sense that Coates is doing some good world-building but in all that exposition, the actual stories themselves are frequently gummed up in monologues. Case in point: T'Challa spends several pages travelling in an astral/dream plane to save Shuri, and he just keeps talking and talking to himself.

The real saving grace is that Wakanda is in a sense the most interesting character in the book.
