At first, I was very taken with this and thoroughly enjoyed a good chunk of it. However, at a certain point the narrative veers into a type of sci-fi I don't enjoy, and it became a slog to finish. Though well written, interesting and with well drawn characters, once the pivot happened I simply lost interest and found the rest of the book slow and long-winded. Regardless of how I felt about the book as a whole I also found the ending disappointing.
