This is a book about the choices we make and the chain reaction that follows . . .

By way of H. G. Wells and Rebecca West's affair, through 1930s nuclear physics, to Flanagan's father working as a slave labourer near Hiroshima when the atom bomb is dropped, this daisy chain of events reaches fission when a young man finds himself trapped in a rapid on a wild river, not knowing if he is to live or to die.

Flanagan has created a love song to his island home and his parents and the terrible past that delivered him to that place.

Through a hypnotic melding of dream, history, science, and memory, Question 7 shows how our lives so often arise out of the stories of others and the stories we invent about ourselves.
