Ola - Burnt offering, sacrifice to the Lord. Only she can save the country from destruction and ward off trouble. But what and who will become this victim? The action of Andrei Valentinov’s new historical and philosophical fantasy takes place in Spain in the 15th century. America has not yet been discovered, Columbus is just preparing his expedition. And along the dusty roads of Castile rides on an absurd horse the withered hidalgo Don Salado - a fighter against giants and sorcerers, a protector of beautiful princesses. But what can he do if ahead is not a windmill, but the Burnt Earth and the Dragon of the Suprema, kindling the fires of the Inquisition with its flame? Or is it still possible? The caravel "Flag of Jesus" raises its sails...The book also includes fragments from historical sources, an interview with the author and responses to the book.
