We Have Always Lived in the Castle

Six years after four family members died of arsenic poisoning, the three remaining Blackwoods—elder, agoraphobic sister Constance; wheelchair-bound Uncle Julian; and 18-year-old Mary Katherine, or, Merricat—live together in pleasant isolation. Merricat has developed an idiosyncratic system of rules and protective magic to guard the estate against intrusions from hostile villagers. But one day a stranger arrives—cousin Charles, with his eye on the Blackwood fortune—and manages to penetrate into their carefully shielded lives. Unable to drive him away by either polite or occult means, Merricat adopts more desperate methods, resulting in crisis, tragedy, and the revelation of a terrible secret.
