El libro extraordinario (Magicornia, 5)

My name is Lucas, I'm Claudia's cousin, and when I grow up I want to be a great magician! In Magicornia, the Bazaar of Amazing Things, a new and very special object appears: the Wishing Lamp. All you have to do is rub it and say something out loud for it to come true. But… be careful what you wish for! Suddenly, books come to life, monsters invade Unicornia, and our favorite hero appears in the real world. Can we fix the mess before it's too late? Will you help me solve this problem?
