Unique and interesting premise and great execution. One small thing I wasn't very keen on throughout the book was the vilification of China, Ukraine and Russia in this entire game and emphasising the idea that UK has had higher standards and regulations from the get go. Whether intended or not, it came off xenophobic and/or chauvinistic.

The ending was also a little too 'and then they lived happily ever after' for me. I think the story would have benefited from

Susan dying

tbh.
