Very good! A wonderful mystery and such a fascinating concept. I enjoyed how the truths of the world slowly unfurled, but not fully until the very end. Despite being relegated to a small island, it didn't feel claustrophobic or constrained to read. It was almost as if I could see it through the eyes of the villagers, who never knew anything else. Abi was a cool concept, being in everyone's mind, the first-person narrator of the book that interacts with everyone. Well executed as well. Enigmatic and compelling!
