Book excerpt: Shortly before Christmas a very brave young girl name Sara makes the acquaintance of Igor, à very particular cat. But apart from Sara no one seems able to see him... The secret of the cats seven lives is in danger. A renegade cat has decided to divulge it to the worst enemy of the feline race, a certain Rator Zybethicus, a malicious muskrat. It does not take Igor much time to persuade Sara to accompany him in this quest through the country's roads and rivers. Dangers meet them all along their way, but they are not the only ones to face them; their friends join them to help them on their mission. It's a charming tale packed with evil muskrats, wise cats, low-life thugs, brave children and worried parents, and it's all sprinkled with fascinating facts about Luxembourg, Echternach and the mystery of cat's multiple lives.
