The fourth book in the “Surprise” series completes the story about a murderous meteorite flying towards the Earth - the books “A Pleasant Surprise”, “A Most Unpleasant Surprise”, “A Strange Surprise”. The story is about a doctor Vladimir from the 21st century, who suddenly finds himself in the 11th century and rushes with a group of friends to the Black Sea to save the world with the help of dolphins. But for this we also need the great poet and mathematician Omar Khayyam, for whom there is a merciless hunt. Will they save him? Won't they save you? Well, at least they will soften the blow? You won't guess! It's easier to read. And that means, move forward with confidence!
