In 1940, as the shadow of war lengthens over Europe, three mysterious travelers enter a village in Spain. They have the appearance of Parisian intellectuals, but the trio of two men and a woman are starving and exhausted from crossing illegally through the Pyrenees. Their story, told over a period of 48 tense hours, is narrated by one of the men, who slowly accepts his unthinkable fate. In a voice despairing and elegant, he calmly considers what he should do, and weighs what any one life means. As he does so, his attention is caught by a five-year-old named Pia who wanders near his cafe table. To Pia he begins to address all that he thinks and feels in his final hours - envisioning a rich future life for her that both reflects and contrasts with his own. Meanwhile, in the 1980s, a woman named Pia seeks solitude on a remote island in the Atlantic, where she works at an inn and reflects on her chaotic childhood. As Pia's story begins, a raging storm engulfs the island and a boat flounders offshore. Pia and her fellow islanders rush to help - and past and present calamities collide. By turns elegiac and heart-pounding, a love letter in the guise of a song of despair, The Certainties is a moving and transformative blend of historical and speculative fiction - a novel that shows us what it means to bear witness, and to attend to those who seek refuge, past and present.
