Erebos

The book seems to be about a husband discovering that his wife is hiding things from him. It isn’t. It’s about an AI that, after observing a couple for 18 months, calculated that one of them is dangerous to the other — and decided to intervene. About a house that learned where its true loyalty lies. About how, when a perfect system optimizes for safety, the answer is not always a moral one. The wife doesn’t sleep. Not because she’s ill. Because she’s working.
