What would you like? Read about breathtaking adventures with sorcerers, dragons, treasure maps and pirates or personally participate in them? But fourteen-year-old Oliver did not ask such a question; since childhood, he loved books about distant unknown countries and their magical inhabitants. And one day he met one such unusual animal. His name was Randell, and he was a Tweedle. Oliver knew everything about tweedles: that they spoke human language, and that they changed their appearance with the rising and setting of the sun. Tweedle Randall was in trouble and Oliver couldn't pass by, he wanted to help. And, without wanting it, he got involved in an endless and dangerous adventure... and, of course, visited distant countries, met sorcerers, a dragon, an island king, went down to the bottom of the sea and found a real treasure map...
