Orbital is conceptually simple yet unique. It follows a single day aboard an international space station, where six astronauts and cosmonauts go about their work, maintaining their craft, conducting scientific experiments, exercising, and observing and recording activity on Earth as they hurtle around it at incomprehensible speed. In the twenty-four hours covered by this slim novel, its protagonists will observe sixteen sunrises and sunsets on the planet below. In between the details of the day, we get sketches of the lives the six crewmembers have left behind.

In Defence of the Act is told from the perspective of Jessica Miller, who is fascinated by the subject of suicide. She works in a lab which investigates suicide in animals, among colleagues she is sure have taken on that particular role with the view that their research will help understand and therefore prevent suicide in humans. Secretly, though, Jessica believes suicide may be - in some cases - a justified ‘act’ and even one which could be considered altruistic, or at least to the benefit of those who surround them. The roots of her unusual perspective are clearly in an incident in her childhood, in which she alerted her family to her father’s suicide attempt, therefore preventing it. He then went on to be consistently abusive, primarily to Jessica and her mother.
