This is one of the best books I have ever read, and it makes me sad that it will probably be marketed and received as an "airport paperback, beach read, psychological thriller" kind of book when it is so much more than that.
I'm still trying to decide how I feel about this. I love The Underground Railroad, and I didn't love this. So in a sense it was disappointing. But in another sense, he did something very clever with this. But in another sense, it was redundant.
