It's about the son of a pepper merchant who finally achieves his dream of visiting the far-away land of Olondria where books are commonplace. However, he ends up haunted by a ghost and consequently becomes a pawn between two religious factions. The story isn't really anything new, but Samatar has created a very beautiful and imaginative world as well as a prose style that is lyrical and evocative making for a very pleasurable read. Plus, there is a undercurrent of a love of books running through the whole thing.
