Brothers Mormarevi are two men, two friends, two authors, who were writing as one person for many years. They are just like Ilf & Petrov. This book is written after the death of the older one – Moritz. When Marko had decided to write this book, he understood that Moritz is sill alive. He describes how they were working, laughing, arguing just as in the old times. “Lily” is not just a book about a little girl, it is a story about children and adults, a book, which is funny and wise at he same time.
