It's a long novel but it didn't feel like it was wasting words. It's a few stories told at once about different people living in different places at different times. One thing that links the stories is none of the main characters are satisfied with the hand they were dealt in life, and the stories explore how they deal with that. Some threads (Constantinople) engaged me sooner than others (Argos), but by the end I was interested in everything, and it all came together in a satisfying way.
There also was some queer representation in the novel, and I like that sort of thing.
