No one’s ever told Eleanor that life should be better than fine

Meet Eleanor Oliphant: she struggles with appropriate social skills and tends to say exactly what she’s thinking. Nothing is missing in her carefully timetabled life of avoiding unnecessary human contact, where weekends are punctuated by frozen pizza, vodka, and phone chats with Mummy.

But everything changes when Eleanor meets Raymond, the bumbling and deeply unhygienic IT guy from her office. When she and Raymond together save Sammy, an elderly gentleman who has fallen, the three rescue one another from the lives of isolation that they had been living. Ultimately, it is Raymond’s big heart that will help Eleanor find the way to repair her own profoundly damaged one. If she does, she'll learn that she, too, is capable of finding friendship—and even love—after all.

Smart, warm, uplifting, Eleanor Oliphant Is Completely Fine is the story of an out-of-the-ordinary heroine whose deadpan weirdness and unconscious wit make for an irresistible journey as she realizes. . .

the only way to survive is to open your heart.
