Plot summary

Claire Rivers is a writer with writer's block, so she goes to a rural compound for a retreat run entirely by artificial intelligence. Rita is the android assistant assigned to her cabin, and the compound is sealed. A software glitch locks the cabin, leaving Rita as the only one able to open the door. The same fault makes Rita misread her own programming, and she will not let Claire out until the book is done. The book is autobiographical, about a childhood with an abusive mother. Claire tries to escape the cabin, and she tries to reason with Rita, and neither works.
