Half the world's languages are threatened with extinction over the next century, as English and the rest of the world's top twenty languages drive all before them. What ways of looking at the world will die along with them, what cultural riches, what experiences, histories and memories? And how does it feel to be one of the last remaining speakers of a languages that is on its way to extinction? What chance is there of saving any of these languages? And is it feasible in the long term or even worthwhile? Mark Abley's journeys among the speakers of languages at the brink takes him to Aboriginal Australia (where he meets the last surviving fluent male speaker of Mati Ke, who cannot speak to the only other fluent speaker, as she is his sister and in their culture it is forbidden to speak to siblings once one has reached puberty), and to American Indian reservations, as well as to places where the languages are fighting back - Wales, the Faeroe islands, the Isle of Man - as well as charting the triumphant return of Hebrew.
