In The Heart Goes Last, bestselling author Margaret Atwood tells the story of Charmaine and Stan, a couple living in their car and surviving almost entirely on tips. Their lives take a drastic turn, however, when they sign up for a ‘social experiment’ that provides them with jobs and a home. The caveat, though, is that the couple must do a stint in a prison cell every second month, while an ‘alternate’ pair occupies their house. According to the publisher, Charmaine and Stan become obsessed with their alternates, and ‘the pressures of conformity, mistrust, guilt and sexual desire begin to take over’.
