What if, one day, Europe was to crack along the length of the Pyrenees, separating the Iberian peninsula?

In Saramago's lovely fable, the new island is sent spinning, like a great stone raft, towards the Azores. While the authorities panic and tourists and investors flee, three men, two women and a dog are drawn together by portents that burden them with a bemusing sense of responsibility. Travelling at first packed into a car, then into a wagon, they take to the road to explore the limits of their now finite land, adrift in a world made new by this radical shift in perspective.
