Despite the heavy rain, the presiding officer at Polling Station 14 finds it odd that by midday on National Election day, only a handful of voters have turned out.

Puzzlement swiftly escalates to shock when eventually, after an extension, the final count reveals seventy per cent of the votes are blank - not spoiled, simply blank. National law decrees the election should be repeated eight days later. The result is worse; eighty-three per cent of the votes are blank. The incumbent government receives eight per cent and the opposition even less. The authorities, seized with panic, decamp from the capital and place it under a state of emergency.

In his new novel, José Saramago has deftly created the politician's ultimate nightmare: disillusionment not with one party, but with all, thereby rendering the entire democratic system useless. Seeing explores how simply this could be achieved and how devastating the results might be.

José Saramago is one of the most important international writers of the last hundred years. Born in Portugal in 1922, he was in his sixties when he came to prominence as a writer with the publication of Baltasar and Blimunda. A huge body of work followed, translated into more than forty languages, and in 1998 he was awarded the Nobel Prize in Literature. Saramago died in June 2010.
