What I knew about this book going in was that it concerned a young woman and a mechanical chess-playing automaton in the early 19th century. I expected intrigues and hoaxes and--given that I bought it though a lesbian book distributor--some amount of queer identity. What I didn’t expect was a dark psychological thriller that kept me on the edge of my seat right up to the end. This is not a fluffy, feel-good comfort read. It’s a gripping adventure and mystery that left me both satisfied and emotionally wrung out.
