Raimundo Siva is a freelance proof-reader for a Lisbon publishing house, who takes it upon himself to insert a negative into the sentence of a history book. Operating on two levels - one in 12th-century Portugal, the other in the 20th century - this extraordinary novel brilliantly mingles past events with a contemporary story of romance, fantasy and historical debate, moving freely between the tenses and continually challenging and teasing the reader. Highly acclaimed in Portugal, Saramago's work now has many international followers, and this edition is an admirable translation. Stimulating stuff! (Kirkus UK)
