Guillermo hates reading, but the rest of his family love it. So, living with them is a daily torture - like having to go to the library once a week, pick a book, read it and write a summary for class. What a pain! Then, one day, he discovers a tiny book hidden behind another far fatter book, The Zippoli Tribe. It's short, it'll take no time to read, he thinks. He opens it with wonder: "Welcome to the Zippoli Tribe, Guillermo. You've taken a long time to find us, but we're not cross. The truth is the Zippoli Tribe never get cross..." Guillermo is super scared: who could be behind this book? He snaps it shut. From here, he discovers that each member of his family reads a different story when they open the book and for the first time he finds a real thirst to know what other stories are hidden in the pages of this tiny, mysterious book.
